Improve Organic Production with Rock Phosphate

“A 35.8% YIELD INCREASE WAS CALCULATED FROM 95 TREATMENT COMPARISONS” Phosphorus (P) is essential for all living organisms. Plants must have phosphorus for normal growth and maturity. Phosphorus plays a role in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and several other processes in plants. In...
