“…The soil pH value of the manure treatment was the highest followed by the CF + M treatment and the lowest pH value was noted in the soil of the CF treatment. These results were in agreement with Benke et al (2009) who stated that the application of cattle manure moved the soil pH towards neutrality in acidic soils, thus improving nutrient availability. The pH decrease in the CF treatment might be attributed to the efficient assimilation of urea by soil microorganisms leading to the production of acidic metabolites such as organic acids (He and Suzuki, 2004) and to the process of nitrification (Hu et al, 2010).…”

A field experiment was conducted to study the effect of repeated manure and mineral fertilizer applications on soil properties and crop yield and their spatial distribution at the plot scale. This experiment was initiated in 1996 with three treatments: 1) chemical fertilizer (CF), 2) chemical fertilizer + manure (CF + M) and 3) manure (M). After continuous application for 18 yr, soil and plants were sampled using 10 m × 10 m sampling grids. The results showed that application of M alone or combined CF + M increased soil total C, total N, organic matter, pH, electrical conductivity (EC) and available P compared with CF. However, M application resulted in significantly higher levels of soil pH and soil EC than for the other treatments. The highest seed yield was observed in M followed by CF + M and the lowest was observed in CF. The contour map indicated there was a medium-to-high spatial distribution for the soil properties and crop yield within and between the treatments. Soil total N content was visually correlated with soil total C, organic matter, soil pH and EC. The contour map of seed yield generally had a high visual correlation with all plant and soil parameters. High spatial distribution of soil properties and crop yield between the treatments clearly showed the effect of organic and mineral fertilizers; however spatial distribution within the treatment might have been due to the uneven distribution of applied fertilizers and soil management practices.

The Effect of Organic and Conventional Farming Systems with Different Tillage on Soil Properties and Enzymatic Activity

et al. 2020

The chemical properties and enzymatic activity of the surface soil horizon were compared between an organic farm (OF) (crop rotation with legume plants, fertilisation with manure) and a conventional farm (CF) (simplified crop rotation, mineral fertilisation, chemical crop protection products). In the years 2001-2017 on the OF (near the village of Juchowo, northern Poland), a reduced tillage system (ploughless) was used, while plough cultivation was used on a CF located in its immediate vicinity. The parameters used to assess the properties of soils were: particle size composition, pH, total organic carbon (TOC) and total nitrogen (TN), dissolved organic carbon (DOC) and dissolved organic nitrogen (DON). The activity of dehydrogenases (DEH), catalase (CAT), alkaline phosphatase (AlP) and acid phosphatase (AcP) and the content of easily extractable glomalin-related soil protein (EEGRSP) were also determined. Sixteen years of soil use in accordance with ecological principles significantly increased the average content of TOC, NT, DOC and DON. Soil samples rich in TOC and DOC showed significantly higher DEH and AcP activity, and EEGRSP content. Statistical analysis showed that the activity of DEH, AlP and CAT in the soil was significantly higher for the OF than for the conventional cultivation system. Limiting soil cultivation procedures on the OF improved the balance of soil organic matter (SOM) and pH value, and significantly increased the content of EEGRSP as compared to the cultivation system used on the CF.

“…The pH serves as a measure of the buffering capacity, and as it approaches neutrality (pH 7), the impact of manure and tillage decreases, as neutral soils are better equipped to buffer ionic charges [20]. The application of solid cattle manure moves acidic and alkaline soil pH towards neutrality [24,25]. Although the field site soils were already close to neutral, the additional organic matter (OM) in manure can still act as a pH buffer, releasing H + in response to alkaline materials and accepting H + in response to acidic materials.…”

Manure, a globally used soil amendment, can contribute to excessive N and P runoff, leading to water pollution. Biochar (BC) shows promise in mitigating nutrient loss by retaining soil nutrients. However, there is limited research exploring the combined effects of tillage practices, biochar, manure, forage crops, and soil types on soil nutrient characteristics in a single field study. Our objectives are to determine if, in North Central Texas, differing soil types, soil amendments, forage crops, and tillage practices affect soil nutrients when applied short term, and whether correlations exist among soil nutrient characteristics as affected by soil amendments, tillage practices, and the presence of forage crops. The study encompasses three field sites with five factors, including soil types, manure rates, biochar rates, tillage practices, and forage crop types. Soil samples were assayed for pH, electrical conductivity (EC), macronutrients, and micronutrients. Data analyses involved variance analysis, Fisher’s tests, and Pearson’s correlations using R in Rstudio (the IDE). Microplots treated with manure (average 2.16 ppm) retained 60% greater average nitrate levels at the end of the growing season than those treated with a synthetic fertilizer (average 1.35 ppm) (p ≤ 0.05). Moderate and strong correlations were observed between EC and S (r (106) = 0.43, p < 0.001 in loamy sand soil; r (106) = 0.80, p < 0.001 in clay loam soil) and between nitrate and Zn, (r (106) = 0.36, p < 0.001 in loamy sand soil; r (106) = 0.44, p < 0.001 in sandy loam soil) across different soil types. Soil type (texture) emerged as the primary influencing factor on plant-available soil nutrients and characteristics, followed by manure application and tillage practices. The impact of BC and forage crop type varied depending on other experimental factors. Understanding the influence of soil type, amendment application, and tillage on soil nutrient characteristics can guide sustainable forage production practices and soil nutrient management strategies.
