Due to a decrease in phosphorus (P) and potassium (K) mining, manure is incinerated to concentrate P and K in ash. To understand the alternative use of manure-derived ash as P and K sources, laboratory and greenhouse experiments were conducted to determine the relationship between ...
Nitrogen(N), phosphorus(P) and potassium(K) are the necessary nutrition elements for tea, and they are closely associated with the yield and quality of tea. With the increasing demand of tea in market, the management of N, P,K elements in the tea garden soil has become one of the most...

Pelletized broiler manure–derived biochar can be used as fast-release potassium fertilizer regardless of pyrolysis temperatures. In contrast, the extraction pattern of phosphorus contained in the biochar significantly differed by pelletizing and pyrolysis temperatures. Plant dry yields and phosphorus up...
P contents in sediments exponentially decreased, while K potentially increased with the size of the particles in the sediments transported in runoff. There was no relationship between organic carbon content in runoff sediments loss and sediment size. 展开 ...
there was no antagonism relationship between them,but there was significant positive correlation between the phosphate concentration of potassium concentralion in leaf epidermal cells;besides the phosphate accumulation was limited by the level of phosphate and calcium.The magnesium concentration of root ...
The effect of nitrogen (N), phosphorus (P), and potassium (K) fertilization on chlorophyll a and b, carotenes, and anthocyanin was studied in muskmelon plants (Cucumis m脙漏lo L. cv. Galia) during their biological cycle. Plants were grown under greenhouse conditions using differential ...
5. But more than 20 million hectares are deficient in phosphorus and potassium. 6. A report from the provincial environmental monitoring center said the lake had been heavily polluted by nitrogen and phosphorus over the past five months.
