Plants Nutrients
N = NITROGEN - For soils that are nitrogen deficient, treat, manure, weeds, grass clippings, and other garden wastes with CBPA and add the resulting compost to the soil. This will result in a simultaneous improvement in humus and nitrogen content.
P = PHOSPHORUS - A natural phosphate rock product can be the best source of phosphorus. Phosphate rock is most effective when applied in combination with manure (3 to 5 lbs. of manure per pound of phosphate). Treat the manure with CBPA and work into the soil. Wait 20 to 30 days and work the phosphate rock into the top layer of soil.
K = POTASSIUM - Sources of potassium include, dead plant material, manure , compost, granite dust, greensand, and seaweed.
Nitrogen - An over abundance of nitrogen can delay flowering while a deficiency can reduce yield.
Phosphorus - is necessary for almost all aspects of plant growth and is essential for flower and fruit formation.
Potassium - is necessary for the formation of sugars, starches, carbohydrates, protein synthesis and cell division in roots and other parts of the plant.
Sulfur - is a structural component and is required for the production of chlorophyll.
Magnesium - is necessary for seed germination and the production of carbohydrates, sugars etc.
Calcium - is a structural component of cell walls and is necessary for cell growth and division.
Iron - is essential for the young growing plants and is necessary for many enzyme functions.
Manganese - is involved in plant enzyme activity for photosynthesis, respiration, and nitrogen metabolism. In highly acid soils an over abundance of iron can result in toxicity.
Boron - is necessary for cell wall formation, membrane integrity and calcium uptake. The functions affected by boron include flowering, pollen germination, fruiting, cell division, water relationships and the movement of hormones.
Zinc - is essential to carbohydrate metabolism, protein synthesis and stem growth. Zinc deficiency may lead to iron deficiency. Lowering soil pH can result in an over abundance of zinc.
Copper - is concentrated in roots of plants and plays a part in nitrogen metabolism. An over abundance of copper can cause toxicity.
Molybdenum - is a structural component of the enzyme that reduces nitrates to ammonia. Without it, the synthesis of proteins is blocked and plant growth ceases.
Chlorine - is involved in osmosis, the ionic balance necessary for plants to take up mineral elements and in photosynthesis.
Nickel - is an essential trace element for plants. It is required to break down urea to liberate the nitrogen into a usable form for plants. Nickel is required for iron absorption. Seeds need nickel in order to germinate.
Sodium - is involved in water movement and ionic balance in plants.
Cobalt - is required for nitrogen fixation in legumes and in the root nodules of non-legumes. The demand for cobalt is much higher for nitrogen fixation than for ammonium nutrition.
Silicon - is found as a component of cell walls. Plants with supplies of soluble silicon produce stronger and tougher cell walls.
