Dynamics of maize carbon contribution to soil organic carbon in association with soil type and fertility level. [PDF]

PLoS ONE, 2015
Soil type and fertility level influence straw carbon dynamics in the agroecosystems. However, there is a limited understanding of the dynamic processes of straw-derived and soil-derived carbon and the influence of the addition of straw carbon on soil ...

Plasma Agriculture: A green technology to attain the sustainable agriculture goal [PDF]

arXiv, 2023
The agriculture sector has many issues such as reductions of agricultural lands, growing population, health issues arising due to the use of synthetic fertilizers and pesticides, reduction in soil health due to extreme use of synthetic chemicals during farming, etc.

N and P constrain C in ecosystems under climate change: Role of nutrient redistribution, accumulation, and stoichiometry

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract We use the Multiple Element Limitation (MEL) model to examine responses of 12 ecosystems to elevated carbon dioxide (CO2), warming, and 20% decreases or increases in precipitation. Ecosystems respond synergistically to elevated CO2, warming, and decreased precipitation combined because higher water‐use efficiency with elevated CO2 and higher ...

Performance Tuning Of J48 Algorithm For Prediction Of Soil Fertility [PDF]

Published in Asian Journal of Computer Science and Information Technology,Vol 2,No. 8 (2012), 2012
Data mining involves the systematic analysis of large data sets, and data mining in agricultural soil datasets is exciting and modern research area. The productive capacity of a soil depends on soil fertility. Achieving and maintaining appropriate levels of soil fertility, is of utmost importance if agricultural land is to remain capable of nourishing ...

Can animal manure be used to increase soil organic carbon stocks in the Mediterranean as a mitigation climate change strategy? [PDF]

arXiv, 2020
Soil organic carbon (SOC) plays an important role on improving soil conditions and soil functions. Increasing land use changes have induced an important decline of SOC content at global scale. Increasing SOC in agricultural soils has been proposed as a strategy to mitigate climate change.

Evaluating the impact of increasing temperatures on changes in Soil Organic Carbon stocks: sensitivity analysis and non-standard discrete approximation [PDF]

arXiv, 2021
A novel model is here introduced for the SOC change index defined as the normalized difference between the actual Soil Organic Carbon and the value assumed at an initial reference year. It is tailored on the RothC carbon model dynamics and assumes as baseline the value of the SOC equilibrium under constant environmental conditions.

Understanding soil fertility in organically farmed systems (OF0164) [PDF]

, 2002
This is the final report of the Defra project OF0164. Organic farming aims to create an economically and environmentally sustainable agriculture, with the emphasis placed on self-sustaining biological systems rather than external inputs.

Functional diversity of farmland bees across rural–urban landscapes in a tropical megacity

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Urbanization poses a major threat to biodiversity and food security, as expanding cities, especially in the Global South, increasingly compete with natural and agricultural lands. However, the impact of urban expansion on agricultural biodiversity in tropical regions is overlooked.

Effect of Seed Priming on Seed Germination and Seedling Growth of Wheat

International Journal of Economic and Environment Geology
Zinc (Zn) is essential for various enzymatic, ionic, and metabolic processes, particularly during seed germination. This study aimed to evaluate the impact of different zinc soaking solutions on the germination and early growth of wheat seeds.

Dynamics of co-composting of pineapple harvest and processing residues with poultry litter and compost quality

Scientific Reports
The production of pineapple generates significant quantities of harvest and processing residues, which are very little used. This study evaluates compost quality using pineapple residues and poultry litter. Five composting treatments were tested, varying
