Corn has a high nutritional requirement, especially with regard to NPK fertilization. However, the low efficiency of conventional fertilizers combined cost input limited reach yields. The use increased seeks mitigate these limitations, reducing potential losses due gradual release nutrients. objective this work was compare nutrition, growth and production maize plants subjected different doses ...
Boreal ecosystems store one-third of global soil organic carbon (SOC) and are particularly sensitive to climate warming and higher nutrient inputs. Thus, a better description of how forest managements such as nutrient fertilization impact soil carbon (C) and its temperature sensitivity is needed to better predict feedbacks between C cycling and climate. The temperature sensitivity of in situ so...
Background and aims: Phosphorus (P) is an essential element for crop growth. However, while links of P turnover in soils to carbon (C) nitrogen (N) availability have been described, it remains be clarified how combinations fertilizer C N additions affect stocks cycling distinct fractions at different soil depths. The objectives our study were (1) assess total are affected by organic amendments ...
Soil degradation is a growing challenge to global agriculture and the United Nations' Sustainable Development Goals (SDGs). This has prompted calls for less use of mineral fertilizer greater reliance on organic fertilizers. However, we need understand better long-term effects usage soil structure guide management practice, as many functions are sensitive pore morphology connectivity. In this st...
ABSTRACT- To investigate the effects of bio-chemical and organic fertilizers on yield and seeds NPK contents of pumpkin (Cucurbita pepo var. styriaca), an experiment was conducted at the Research Farm of Kurdistan University in 2009 growing season. Treatments were included 1) control, 2) seeds inoculated with free-living N fixing bacteria (NFB), 3) seeds inoculated with phosphate-solubilizing b...
Cropping systems with legumes play key roles in farming sub-Saharan Africa. However, how commonly legume associations perform low input-systems is not well-known. Here, we studied four species used three rotation upland rice, i.e., groundnut monocropping, sorghum–cowpea intercropping, and velvet bean–crotalaria two fertilization managements on the previous manure alone or complemented mineral f...
The crucial trend in the intensification of gardening is use agrochemicals, including systematic application mineral fertilizers, regulated by production flow chart fruit products. Technological pressure on soil causes aggravating ecological problem loss fertility level conditions orchard monoculture. search for sustainable and environmentally effective approaches to solving managing factors ai...
Repeated fertilizer applications to cultivated soils may alter the composition and activities of microbial communities in terrestrial agro-ecosystems. In this study, we investigated the effects of different long term fertilization practices (control (CK), three levels of mineral fertilizer (N1P1K1, N2P2K2, and N3P3K3), and organic manure (OM)) on soil environmental variables and microbial commu...
This study evaluated the effects of N/P fertilization on chemical, mineral composition, and in vitro degradation kinetics cactus pear cv. Gigante. The research was conducted Quixadá Tejuçuoca, CE, Brazil. Nine combinations were from five levels N (10, 70, 100, 130, 190 kg ha−1 year−1), P2O5 two harvest frequencies (annual biannual). experiment performed a split [...]
