Answer 2

Are there only three most important nutrients? I always thought they were all equally important including all of the minors.

Answer 3

Nitrogen: (For producing leaf growth and greener leaves because it t is an essential building block of chlorophyll. With a good supply, plants grow sturdily and mature rapidly, with rich, dark green foliage.)
Dried blood 12-15
Cottonseed meal 7
Bone meal 4
Coffee grounds 2
Cocoa bean & peanut hulls 1
Weeds & grass clippings 0.9
Compost manure 0.5

Phosphorus: (For proper seed development, it is essential to the distribution and storage of that energy in the form of sugars and starches; hastens maturity; increased seed yield and flower production; fruit and vitamin content; increased resistance to winterkill and diseases)
Phosphate rock 30-32
Bone meal 21
Dried blood 3
Cottonseed meal 2.5

Potassium: (regulates the processes of plant food creation, transportation, and storage that are fueled by nitrogen and facilitated by phosphorus. For promoting early growth; improves stem strength as it is part of the fluid that fills plant tissues, contributing to the ability of stems and leaves to hold themselves upright; better color, flavor and keeping quality of fruits and vegetables; good for root system: protects them from the cold and protects during dry weather by preventing excessive water loss.)
Basalt rock; wood ashes 7
Granite dust 5
Greensand 5
Seaweed (kelp) 5
