The invention discloses a high-phosphorus high-potassium controlled-release fertilizer for peanuts and a preparation method of the high-phosphorus high-potassium controlled-release fertilizer, belonging to the technical field of fertilizers. The high-phosphorus high-potassium controlled-release fertilizer ...
Nitrogen and energy use efficiency were calculated as partial factor productivity of N and energy, respectively (i.e. grain yield divided by either total N input or energy input). Energy inputs in this study were calculated using only on-farm input data (i.e. fertilizer rate, seed rate, d...

HFCS contains amounts of riboflavin, niacin, pantothenic acid, folic acid, vitamin C, calcium, iron, magnesium, phosphorus, potassium, sodium, and zinc (Parker et al., 2010). The moisture content of this syrup is between 23% and 29% (White, 2014). ...

CALCIUM, phosphorus and potassium play a vital role, but they can have adverse affects if their supplies are in excess or are deficient. AGA Soil Technology can test soils for the availability of the nutrients, and then advise farmers on how to better their "management skills'', so crops ...
The mean temperature and rainfall statistics for the maize growth seasons of the two years are shown in Fig. 5. The test region is defined by its brown loam soil, and the organic matter, alkali-hydrolysable nitrogen, available phosphorus, and available potassium contents in the top 20 cm of...
Calcium has many uses. It's an ingredient in antacids, and doctors use it to control high levels ofmagnesium, phosphorus, and potassium in your blood. It may also ease premenstrual syndrome (PMS) symptoms and help prevent certain cancers. Some research shows that calcium with vitamin D may ...
Throughout the duration of the trial the pH, conductivity, nitrogen, phosphorus and potassium concentrations of the FDW were consistent and without significant differences, although biochemical oxygen demand (BOD) levels did differ significantly between years (2753卤259mgL 1 ). Soil, ground and ...
Soil tests of surface soils to a 15cm depth did not prove useful in predicting Zn and Mn nutrition of trees, as all soil samples had medium or high levels of DTPAextractable Zn and Mn. Phosphorus (P) and potassium (K) were low in more than 20% of the leaf samples and high in ...
