Influence of long-term residue management on soil enzyme activities in relation to soil chemical properties of a wheat-fallow system

Soil accelerator activities (acid and alkalescent enzyme, arylsulfatase, β-glucosidase, enzyme and amidase) were determined (0- to 20-cm depth) once fifty five years of crop-residue and N-fertilization treatment in an exceedingly winter wheat (Triticum aestivum L.)-fallow system on dry soils of the geographic region. All residues were incorporated and therefore the treatments were: straw (N0), straw with fall burn (N0FB), straw with spring burn (N0SB), straw and forty five weight unit N ha−1 (N45), straw and ninety weight unit N ha−1 (N90), straw burned in spring and forty five weight unit N ha−1 (N45SB), straw burned in spring and ninety weight unit N ha−1 (N90SB), straw and a pair of.24 T ha−1 pea-vine residue and straw and twenty two.4 T ha−1 of straw-manure. accelerator activities were considerably.

Changes in Soil Chemical Properties Resulting from Organic and Low-Input Farming Practices

Soil chemical properties throughout the transition from standard to organic and low-input farming practices were studied over eight period in California’s state capital natural depression to document changes in soil fertility standing and nutrient storage. Four fanning systems differing in crop rotation and external inputs were established ashore antecedently managed conventionally. Fertility within the organic system trusted animal manure applications and winter cover crops; the 2 standard systems received synthetic plant food inputs; the low-input system used cover crops and animal manure throughout the primary three period and canopy crops and artificial fertilizer for the remaining five yr. At four and eight period once institution, most changes in soil chemical properties were per predictions supported nutrient budgets. Inputs of C, P, K, Ca, and Mg were higher within the organic and low-input systems as a results of manure applications and canopy crop incorporations. [2]

Effects of the application of charred bark of Acacia mangium on the yield of maize, cowpea and peanut, and soil chemical properties in South Sumatra, Indonesia

Charred bark of tree mangium (bark charcoal), that is formed of wood waste from pulp production, was applied as soil change for the cultivation of maize, cowpea and peanut to look at its effects on crop yield and soil chemical properties in South island, Indonesia. The yields of maize associate degreed peanut considerably enhanced once the appliance of bark charcoal underneath a inseminated condition in an unproductive soil atmosphere. additionally, will increase within the root quantity and establishment rate of arbuscular mycorrhizal (AM) fungi once bark charcoal application were additionally determined in maize. In general, the appliance of bark charcoal iatrogenic changes in soil chemical properties by increasing the pH scale worth, total N and offered P2O5 contents, ion exchange capability, amounts of exchangeable cations and base saturation, and by decreasing the content of exchangeable Al3+.

Less abundant bacterial groups are more affected than the most abundant groups in composted tannery sludge-treated soil

The application of composted work sludge (CTS) has promoted shifts in soil chemical properties and, therefore, will have an effect on the soil microorganism community. This study assessed the result of the CTS on the soil microorganism community over time. The CTS was applied at 5 rates (0, 2.5, 5, ten and twenty t/ha), and therefore the microorganism community was evaluated for a hundred and eighty days. The principal curve response (PRC) analysis showed that the foremost easy phyla weren’t influenced by the CTS rates over time, whereas the analysis of the microorganism community showed that a number of the less easy phyla were influenced by the CTS rates. Similarly, the PRC analysis for the microorganism categories showed the numerous result of the CTS rates. [4]

Effects of Poultry Manure on Some Soil Chemical Properties and Nutrient Bioavailability to Soybean

Organic manures area unit identified to be wealthy sources of each macro and small nutrients of the crop. They conjointly facilitate in up the physical standing of the soil. Pot experiments were dole out to work out the consequences of poultry manure on some soil chemical properties pH scale, organic C, obtainable P, exchangeable Ca, Mg, K, Na, and Effective ion Exchange capability i.e. ECEC) and dry matter yields, plant heights, concentrations of N, P and K in plant tissues of soybean plants. 5 soil samples collected from analysis farms in Federal University of Agriculture, Abeokuta (FUNAAB), Odeda, Ayetoro, Ibadan, Ikenne in South Western African nation, were used for the screen house pot experiment.
