phosphorus (P), and potassium (K) — the three primary macronutrients plants need in the largest quantities. The three numbers on every fertilizer bag (e.g., 10-10-10 or 46-0-0) are the guaranteed analysis: the percentage by weight of available N, P₂O₅ (phosphate), and K₂O (potash) in that order. A bag labeled 21-0-0 contains 21% nitrogen and no phosphorus or potassium. A 4-18-38 label means 4% nitrogen, 18% phosphate, and 38% potash. Note that P and K values are expressed as P₂O₅ and K₂O rather than elemental phosphorus and potassium — this matches how soil fertility is reported on fertilizer labels industry-wide. Secondary nutrients (calcium, magnesium, sulfur) and micronutrients (iron, zinc, manganese, copper, boron, molybdenum) are listed separately when present in guaranteed amounts.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eCan I use water-soluble fertilizers in organic gardens?\u003c\/summary\u003e\n    \u003cdiv\u003e\n      \u003cp\u003eNot all water-soluble fertilizers are approved for certified organic production — most synthetic water-solubles (Urea, Calcium Nitrate, MAP, MKP, Potassium Sulfate) are not OMRI listed and are not permitted in certified organic programs. However, some water-soluble products derived from organic sources may qualify. If organic certification matters for your operation, check individual product pages for OMRI status and consult your certifying agency. For home gardens without certification requirements, synthetic water-solubles are widely used alongside organic amendments.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat's the difference between soil application and foliar feeding?\u003c\/summary\u003e\n    \u003cdiv\u003e\n      \u003cp\u003eSoil application delivers nutrients to the root zone — either as a dry broadcast\/incorporation or dissolved in irrigation water (fertigation). Nutrients are taken up through the root system over time. Foliar feeding involves spraying a dilute fertilizer solution directly onto leaves for rapid absorption through the leaf surface — useful for correcting acute deficiencies quickly or supplementing during high-demand growth stages. Foliar feeding is not a substitute for healthy soil nutrition; it's most effective as a targeted supplement. Only water-soluble fertilizers should be used for foliar applications. Apply in the early morning or evening when temperatures are below 85°F and foliage is dry — never during heat stress or midday sun.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eHow do I know if my plants have a nutrient deficiency?\u003c\/summary\u003e\n    \u003cdiv\u003e\n      \u003cp\u003eMost nutrient deficiencies produce visible symptoms on leaves — the pattern tells you which nutrient is involved. Yellowing that starts on older, lower leaves typically indicates nitrogen or magnesium deficiency (mobile nutrients). Yellowing between leaf veins on young, new leaves (interveinal chlorosis) is the classic sign of iron, zinc, or manganese deficiency (immobile micronutrients). Stunted new growth with short internodes suggests zinc deficiency. Purple or reddish leaf undersides can indicate phosphorus deficiency, especially in cold soils. A soil test is the most reliable way to confirm which nutrients are genuinely deficient before purchasing amendments.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eAre Greenway Biotech fertilizers safe for edible crops?\u003c\/summary\u003e\n    \u003cdiv\u003e\n      \u003cp\u003eYes.

It supplies modest, slow-release nitrogen and an equal amount of soluble potash (K₂O), adds organic matter, and feeds the beneficial soil microbes that cycle nutrients to plants — which makes it a long-favored choice for roses, vegetable and flower beds, trees and shrubs, and compost activation.\u003c\/p\u003e\n\u003cp\u003eNutrients become available gradually over roughly 4 to 8 weeks as soil microbes mineralize the meal, so alfalfa meal feeds steadily without the flush-and-crash cycle of soluble fertilizers, and carries low burn risk at recommended rates.

It contains no available phosphate, so pair it with a phosphorus source for a complete program. It has a near-neutral to slightly alkaline reaction and is not recommended for acid-loving plants such as blueberries, azaleas, and rhododendrons. Microbial breakdown slows in cold or sterile media.

As soil bacteria convert the ammonium to nitrate, hydrogen ions are released and soil pH drops gradually, which makes ammonium sulfate well suited to alkaline soils and to crops that need an acidic root zone.
