Article Synopsis
- - The study explored the use of different types of biochar (from animal manures and plant residues) as soil amendments to improve nutrient retention in acidic soils for wheat and soybeans in a no-tillage system.
- - Results showed that applying biochar significantly influenced nutrient levels (NPK) and soil pH in the top 5 cm of soil, while deeper layers did not show the same impact, indicating varying effectiveness based on soil depth.
- - Overall, biochar improved nutrient retention and soil conditions (increased pH, reduced exchangeable Al) in surface soil, but its performance varied depending on nutrient type and soil depth, highlighting the need for careful application in sustainable farming.
Article Synopsis
- Intermittent irrigation in rice cultivation can reduce methane and nitrous oxide emissions, making it a promising environmental strategy.
- The study compared five irrigation practices, finding that continuous irrigation resulted in the highest methane emissions, while intermittent irrigation significantly lowered these emissions.
- Soil moisture conditions greatly influence emissions and plant growth, with the best results observed when flooding is initiated at saturated soil conditions.
Renewing carbon and re-establishing it again in the soil is one of the valuable means to cope with climate change. There are many technologies for carbon apprehension and storage, but the most important one gaining attention is biochar technology. So, to carbonize and return different biological materials back to the farmland, a comprehensive study was proposed to characterize and evaluate the carbon (C) mineralization of biochars produced from different animal manures and crop straws.

High copper (Cu) soil contents, due to the continuous vineyard application of Cu fungicides throughout the years, may impair the growth of the shoot and modify the structure of the root system. The current study aimed to investigate the threshold levels of available Cu in the soil causing toxicity effects in young grapevine plants of 'Red Niagara' cultivated in clay soils. Grapevine plantlets were cultivated in pots containing vineyard devoted soils with increasing contents of available Cu (25, 80, 100 and 165 mg kg), for 53 days.
