Soil solutions from three P-deficient Cambisols were analyzed for inorganic orthophosphate (Pi), organically combined phosphorus (Po), total phosphorus (Pt) and residual phosphorus (Pr=Pt(Po+Pi)). The solutions were obtained by centrifugation of soil samples wetted-up to 90% field capacity. ...
The presence of toxic metals in soil can severely inhibit the biodegradation of organic contaminants [6]. Heavy metal contamination of soil may pose ... RA Wuana,FE Okieimen - 《Isrn Ecology》 被引量: 1100发表: 2011年 Combined Use of Organic and Inorganic Nutrient Sources for Soil ...

On average, Tithonia with half recommended rate of inorganic fertilizer recorded the highest (4.8 Mg ha−1) maize yield followed by sole Tithonia (4.7 Mg ha−1). Highest average concentration (144.8 and 115.5 kg N ha−1) of mineral N was recorded at the 30–100 cm soil depth at ...
The increasing demand of food causes an excessive exploitation of agricultural lands, often inducing phenomena of soil sickness accompanied by the development of soilborne diseases. The use of residual biomasses together with inorganic fertilizers can be
Erosion: One controlled, replicated trial from India found that mixed amendments were more effective at reducing the size of cracks in dry soil than inorganic fertilizers alone or no fertilizer. SOC loss: Four controlled, randomized, replicated trials and one controlled trial from China and India ...
Understanding the effects of external organic and inorganic components on soil fertility and quality is essential for improving low-yielding soils. We conducted a field study over two consecutive rice growing seasons to investigate the effect of applying chemical fertilizer (NPK), NPK plus green manure...
Effects of organic soil amendments on populations of mycophagous springtails and nematodes and on Rhizoctonia solani stem canker of potato were investigate... M Lootsma,K Scholte - 《Nippon Ishinkin Gakkai Zasshi》 被引量: 76发表: 1998年 Influence of organic and inorganic soil amendments on pla...
Soil microbial biomass is the main driving force in the decomposition of organic materials and is frequently used as an early indicator of changes in soil properties resulting from soil management and environment stresses in agricultural ecosystems This
decline in aggregate size. The accumulation of total nitrogen within <1 mm aggregates under NPKS might play a key role in maintaining the survival of soil nematodes. In our study, both crop straw incorporation and inorganic fertilizer application effectively improved soil physicochemical properties ...
