  • GYPSUM FERTILIZER FOR BLUEBERRIES AND METHOD

    The purpose of the present invention is to provide a gypsum fertilizer for blueberries and a method for suppressing blueberry abscission that can suppress abscission of blueberry fruits without adversely affecting the growth of the blueberry fruits, and not only increases the crop yield but also eliminates the need for frequently collecting fallen fruits, thus yielding a major practicalGypsum as an agricultural product February 6, 2019 Susan V Fisk Warren Dick has worked with gypsum for more than two decades You’d think he’d be an expert on drywall and plastering because both are made from gypsum But the use of gypsum that Dick studies might be unfamiliar to you: on farmlandGypsum as an agricultural product | Soil Science SocietyTo produce a phosphorus fertilizer, the rock is treated with acid; sulfuric, phosphoric or nitric Each method has its advantages and constraints The sulfuric acid route produces a low phosphorus fertilizer – singleHow we make our fertilizer | Yara International
