Organic production methods which include the exclusion of chemical approach of soil amendment have been observed to improve plant growth and preserve the soil health and biodiversity of production environment. A study was conducted at the Federal University of Agriculture, Abeokuta, to examine the influence of organic manure and wood ash on the abundance of soil microorganisms, organic carbon and yield of soybean in acid soil. The study consisted of three rates of wood ash (0, 2.5 and 5.0 t ha-1) and three rates of cow dung (0, 5.0 and 10.0 t ha-1) arranged in completely randomized design, replicated three times. Soybean variety TGX 1485 – ID was sown into 5 kg. The results showed that wood ash application at 5.0 t ha-1 significantly increased the soil pH (6.6), organic carbon (7.48) and soil microbial population (110 × 104 cfu g-1) compared to lower rate of 2.5 t ha-1 and control, which resulted in highest number of pods (7.7) and grain yield (14.2 g per plant) at harvest. Cow dung treatment of 10 t ha-1 significantly had highest soil organic carbon (7.39%) at 8 WAP and soil microbial population (21.1 and 91.4 × 104 cfu g-1) at 4 and 8 WAP respectively. These findings indicate that application of wood ash may be an acceptable alternative liming agent to the inorganic soil amendment and higher soybean productivity.

An investigation was carried out during three consecutive years from 2016-17 to 2018-19 at farm of B.P.S. Agricultural college, Purnea on Mango cv. Amrapali to study the effect of conservation practice of mulch with irrigation and fertilizer levels on yield and soil parameter, fruit yield and its qualities of mango grown in kosi zone of Bihar. The experiment was laid out in split split plot design with three replications. Experimental findings revealed that conservation practices as mulch significantly increased fruit set, fruit retention, fruit yield and fruit quality. Among different irrigation levels and fertilizer doses maximum fruit yield (23.24 ton/ha) was obtained under conservation practice with 75% recommended irrigation along with 100% RDF which was at par with conservation practice with 75% recommended irrigation along with 75% RDF. Conservation treatment also showed maximum TSS (23.69° Brix) with maximum (0.39%) acidity of fruit. Observations also revealed that conservation practices as mulching significantly increased the soil moisture content, organic carbon %, available soil N, P and K, along with increase soil microbial population. Among the different fertilizer levels highest organic carbon %, available soil N, P and K, as well as soil microbial population were observed with 100% RDF, however only organic carbon and available soil P were at par with 75% RDF.

Carbon and microbes in the soil fluctuated from time to time due to various things. This study aims to determine the dynamics of carbon and microbes in the soil in the treatment of biochar-compost. In addition to the use of biochar-compost, this research also uses nano biochar and enrichment with microbial consortia. The study was conducted at the screen house using a complete randomized design with three replications with following treatments: control / without organic fertilizer (P0), compost (P1), biochar-compost 1: 4 (P2), nano-biochar-compost 1: 4 (P3 ), biochar-compost + microbial consortia (P4), compost + microbial consortia (P5) and biochar-compost + microbial consortia (P6) with a dose of 2.5 tons/ha respectively. Biochar comes from corncobs. Compost biochar plus application was made before planting.  Parameters observed were soil carbon (C-organic), soil acidity (pH) at 7 DAA, 37 DAA and after harvest, and the total soil microbial population at 2 DAA and after harvest. Soil carbon was measured using Walkey and Black method measured by spectrophotometer, soil pH using a soil: water ratio = 1: 5 and measured by a pH meter, the total microbial population using Total Plate Counting (TPC) method. The results showed carbon and soil microbial populations decreased over time, except for microbial communities in a single compost treatment.

Kinetics Of

We tried to develop deterministic models for kinetics of 2,4-D breakdown in the soil based on the following considerations: (i) at low concentrations degradation results from maintenance consumption by a large fraction of the soil microbial population; (ii) at high concentration in addition to the maintenance consumption there is a growth-associated carbon incorporation by a small specific microbial population. Values for the biokinetic parameters are consistent with those commonly found in the literature. Comparison between observed and simulated curves suggests that a non-negligible part of the pesticidal carbon exists as microbial by-products.
