Best 16 4 8 Fertilizer for Lawns, Pastures, and Liquid Feeding

#1 · Best Overall

1. The Andersons PGF Complete

• Form: Granules
• Weight: 18 lb

Best for: Fine-granule turf feeding.

Why it ranks #1: Its 16-4-8 granules suit all turf types and combine fine distribution, iron, micronutrients, Humic DG, and feeding for up to eight weeks.

Super-fine granules provide twice as many particles per square foot, helping distribute this 16-4-8 fertilizer evenly across turf. The Andersons pairs that coverage-focused format with quick- and slow-release nitrogen, so lawns receive immediate feeding followed by nutrition for up to eight weeks.

The 4-1-2 nutrient ratio supplies nitrogen, phosphorus, and potassium, while iron, micronutrients, and Humic DG add to the product’s total-nutrition approach. Quick- and slow-release nitrogen supports feeding for up to eight weeks, with reapplication recommended every six to eight weeks. Its granules suit use on all turf types at any time during the growing season. Wear gloves, goggles, and a dust mask when handling; the product is not for sale in California.

Skip it if you need a liquid application; Simple Lawn Solutions 16-4-8 Advanced is a liquid fertilizer with a hose-end sprayer.

A fit for turf owners who want fine granular coverage, added micronutrients, and feeding that spans several weeks. Its California sales restriction matters, and application requires protective gloves, goggles, and a dust mask.

#2 · Largest Stated Coverage

2. PROXIO Lawn Fertilizer

• Form: Granules
• Weight: 40 lb

Best for: Large-lawn granular coverage.

Why it ranks #2: This granular 16-4-8 option lists coverage of 11,000 square feet, humic and fulvic ingredients, and quick- and slow-release feeding up to eight weeks.

Coverage of up to 11,000 square feet makes PROXIO’s 40-pound 16-4-8 granular fertilizer a practical option for treating a broad lawn in one product. Fine particles support even distribution, while quick- and slow-release nitrogen provides feeding for up to eight weeks.

The formula combines nitrogen, phosphorus, and potassium with iron, micronutrients, and organic Humic DG and fulvic acid. The listed humic ingredients support soil and root benefits, while the nitrogen release mix supplies ongoing nutrition. Fine granules are described as covering twice the area per square foot and can be applied with most lawn spreaders, helping fit the product into familiar spreading routines. The 40-pound package and stated coverage are useful planning details for larger turf areas.

Skip it if you prefer a ready-to-use hose-end liquid; Simple Lawn Solutions 16-4-8 Advanced includes a sprayer.

Choose it for a broad lawn where granular spreading and up-to-eight-week feeding suit your routine. Its 40-pound weight and granular application are important considerations if you prefer a smaller package or liquid feeding.

#3 · Broad Liquid Coverage

3. Prevegenics Liquid Fertilizer

• Form: Liquid
• Weight: 2 lb

Best for: Broad-coverage liquid feeding.

Why it ranks #3: The 32-ounce liquid formula states coverage up to 10,000 square feet and includes iron, L-amino acids, and fulvic acid for lawn use.

Coverage of up to 10,000 square feet is the central draw of Prevegenics 32-ounce 16-4-8 liquid fertilizer. Its balanced nitrogen, phosphorus, and potassium formula is paired with iron, L-amino acids, and fulvic acid, giving lawn owners a liquid option with several listed ingredients.

Prevegenics presents this product as a liquid lawn food for all grass types, with the 16-4-8 ratio supplying the three primary nutrients. The listing links its formula to green-up, root development and strengthening, and nutrient translocation. Iron, L-amino acids, and fulvic acid distinguish the ingredient mix, while stated coverage of up to 10,000 square feet helps buyers estimate whether one bottle suits their lawn. No application directions are supplied in the provided details.

Skip it if you want application steps included; Simple Lawn Solutions 16-4-8 Advanced lists hose-end spraying directions.

Consider it for a liquid-feeding routine when broad stated coverage and the included iron, L-amino acids, and fulvic acid match your priorities. Buyers who need listed application steps should account for their absence here.

#4 · Seaweed and Fish

4. Simple Lawn Solutions 16-4-8

• Form: Liquid
• Weight: 2 lb

Best for: Hose-end liquid lawn feeding.

Why it ranks #4: This 32-ounce liquid lawn food lists a 16-4-8 ratio, seaweed and fish, and hose-end sprayer directions for straightforward application across grass types.

A ready-to-use sprayer makes Simple Lawn Solutions Advanced 16-4-8 a hose-end liquid option for lawn owners who want to apply fertilizer without spreading granules. Its balanced NPK formula also contains seaweed and fish, pairing the application format with additional ingredients.

The directions are straightforward: shake the bottle, connect the hose end to the sprayer, attach it to a water hose, then spray evenly over the lawn. That workflow avoids a separate granular spreader. The 16-4-8 blend supplies nitrogen, phosphorus, and potassium for lawn greening and growth, while seaweed and fish are included in the formula. The product is described for all grass types, including Bermuda, so it can suit varied turf rather than a single named grass.

Skip it if you want granular feeding without a hose; The Andersons Professional PGF Complete 16-4-8 is a granular fertilizer.

A practical match for lawn owners who want a hose-end application and a liquid 16-4-8 formula with seaweed and fish. It is less suited to sites without convenient water-hose access.

#5 · One-Gallon Liquid

Best for: Spring and summer liquid feeding.

Why it ranks #5: The gallon-size liquid fertilizer combines fast- and slow-release nitrogen with seaweed extract and is described for spring and summer use on all grass types.

Fast- and slow-release nitrogen combine in LawnStar’s liquid 16-4-8 lawn food, pairing quick green-up with longer-lasting feeding. Added seaweed extract and a formula described for all grass types make it an option for owners seeking a liquid spring or summer application.

LawnStar also includes highly bioavailable seaweed extract. The product is identified as a liquid and is intended for spring and summertime use, which helps define its seasonal fit. The supplied information does not provide an application rate or instructions, so buyers needing those details should consider that gap.

Skip it if you need hose-end directions; Simple Lawn Solutions 16-4-8 Advanced supplies steps for hose-end spraying.

#6

6. Reed & Perrine Turf Fertilizer

Best for: Extended-release southern lawn feeding.

Why it ranks #6: This granular 16-4-8 fertilizer states a 3-to-4-month release time and 8,000-to-10,000-square-foot coverage, appealing to buyers prioritizing longer feeding.

A stated three-to-four-month release time sets Reed & Perrine Turf Fertilizer apart for buyers seeking longer-lasting granular feeding. Its 16-4-8 formula is described as containing slow-release fertilizer and iron, with spring application noted for jump-starting the greening of southern lawns.

The product’s slow-release formulation is intended to extend nutrient delivery over three to four months, which can suit a lawn-care schedule with fewer feeding windows. Its listed coverage is 8,000 to 10,000 square feet, giving buyers a basis for planning an application area. The description specifically highlights iron for greening southern lawns when outside temperatures are cool and recommends spring use to jump-start turf greening. The supplied listing gives no application rate or spreader details.

Skip it if you need a specified application rate; SeedRanch Pasture Safe 16-4-8 lists rates per area.

A fit for southern lawn owners seeking a longer release window and spring feeding, especially when cool temperatures affect greening. Check the supplied product information carefully if you need application-rate or spreader guidance.

#7

7. PetraMax Liquid Fertilizer

• Form: Liquid
• Weight: 9 lb

Best for: Humate-enriched liquid lawn food.

Why it ranks #7: The one-gallon liquid 16-4-8 formula is described for all grass types and adds humates and potassium to support lawn growth and root development.

High-purity humates and supplementary potassium distinguish PetraMax 16-4-8 liquid fertilizer, linking its balanced nutrient formula to stated support for deeper root development. The concentrate is described for all grass types and for spring and summer lawn applications.

The 16-4-8 formula supplies nitrogen, phosphorus, and potash, while the listing identifies high-purity humates and additional potassium as part of its root-development emphasis. Petra describes the nutrient blend as supporting lawn growth and green grass across all grass types. Its liquid concentrate form suits buyers seeking a liquid product rather than granular fertilizer, and the spring-summer application focus narrows its stated seasonal role. The supplied details do not give a dilution rate or application directions.

Skip it if you need listed hose-end directions; Simple Lawn Solutions 16-4-8 Advanced provides hose-end application steps.

Consider PetraMax if you want a liquid 16-4-8 concentrate with humates and a stated spring-summer fit for varied grass types. Plan around the fact that dilution and application instructions are not supplied here.

#8

8. Simple Lawn Solutions Bundle

• Form: Liquid
• Weight: 2 lb

Best for: Lawn food and green-color bundle.

Why it ranks #8: This bundle pairs 32-ounce 16-4-8 liquid lawn food with 32-ounce liquid iron, combining macronutrients and an additional iron product for lawn greening.

This Simple Lawn Solutions bundle pairs 32 ounces of 16-4-8 liquid lawn food with 32 ounces of Dark Green liquid iron. The combination addresses both macronutrient feeding and deeper green color, giving buyers two distinct liquid products in one lawn-care set.

The 16-4-8 lawn food supplies nitrogen for greening and growth, phosphorus for plant and root development, and potassium as part of its balanced NPK formula. The included Dark Green liquid iron is described as adding micronutrients for a deep, dark green result. Together, the products target lawn nutrition and color rather than relying on the NPK fertilizer alone. The supplied details do not specify application directions, timing, or coverage, so those planning details remain unresolved.

Skip it if you want one liquid fertilizer rather than a bundle; Prevegenics 16-4-8 Liquid Lawn Fertilizer is a single product.

A match for lawn owners seeking both balanced NPK feeding and a separate liquid iron product for deeper green color. Consider the missing coverage and application details before planning how the two products fit your routine.

#9

9. SeedRanch Pasture Fertilizer

• Form: Granules
• Weight: 50 lb

Best for: Established pasture fertilizing.

Why it ranks #9: Its exact 16-4-8 ratio and stated pasture-safe use suit established pasture, with a listed application rate of 50 pounds per 10,000 square feet.

Pasture-safe labeling and an explicit rate of 50 pounds per 10,000 square feet distinguish SeedRanch’s 16-4-8 granules for established pasture. The product also lists an acre-based rate, making it easier for pasture managers to plan quantities across larger measured areas.

SeedRanch specifies use on established pasture, with spring and fall identified as the best times to fertilize. The rate is 50 pounds per 10,000 square feet, or 200 pounds per acre, so buyers can match the stated quantity to either a smaller measured plot or acreage. Its granular form supports a conventional spread application, though the supplied listing does not identify a particular spreader or give additional application instructions. The product is specifically presented for pasture rather than general lawn use.

Skip it if you need feeding for a general lawn; The Andersons Professional PGF Complete 16-4-8 is listed for all turf types.

A clear choice for established pasture owners who can plan by the stated area-based rates and spring or fall timing. Its pasture focus may not suit buyers looking for a general turf fertilizer.

#10

10. PetraTools Liquid Nitrogen

• Form: Liquid

Best for: Nitrogen-focused green-up.

Why it ranks #10: This liquid is a 28-0-0 nitrogen product rather than 16-4-8, so it does not match the searcher's requested balanced fertilizer ratio.

A 28-0-0 formula with 70% quick-release and 30% slow-release nitrogen makes this PetraTools liquid fertilizer a nitrogen-focused option, not a balanced 16-4-8 feed. It targets lawns needing nitrogen for faster greening and ongoing growth between applications.

PetraTools describes the product as a liquid nitrogen supplement for grass with nitrogen deficiency, using quick-release nitrogen for rapid green-up and slow-release nitrogen for continued growth. The listed directions call for mixing it with water in a sprayer and spraying evenly, ideally at one gallon per 1,000 square feet. Because its NPK is 28-0-0, it supplies no listed phosphorus or potassium, making it distinct from the balanced 16-4-8 products in this roundup.

Skip it if you need balanced 16-4-8 nutrients; Petra PetraMax Liquid Lawn Fertilizer for Lawns Concentrate is a 16-4-8 formula.

Choose this PetraTools product when nitrogen deficiency and rapid green-up are the priority, and its stated sprayer rate suits your lawn. It is not the right match when you specifically need balanced 16-4-8 nutrients.
