The adoption of crops that precede the renewal sugarcane fields, improves soil physical conditions, through addition organic matter, increase biopores and greater aggregation. This work aimed to evaluate attributes after usage crops, in conventional tillage (CT) no-tillage (NT), at time ​​renewal. experimental design was a randomized block design, with five replicates. treatments consisted use Crotalaria juncea, ochroleuca, Helianthus annuus (sunflower), Glycine max (L.) Merrill (soybean), Sorghum bicolor Moench, sorghum variety saccharine BRS 506, fallow treatment. After crop vegetative cycle potential ​​renewal, samples were collected, preserved structure, using metallic cylinder determine density (SD), microporosity (Micro), macroporosity (Macro) total porosity (TP) also collected aggregates stability, geometric mean diameter, weighted diameter (ASI, GMD, WMD, DI). C. juncea cultivation favoured lowest values ​​of SD where CT performed. Treatment sunflower, soybean NT. increased Macro TP on CT. In NT sunflower PT. cultivars highest (GMD), (WMD) aggregate stability index (IEA). treatment favored dispersion (DI). cultivations sorghum, it is not necessary stir soil.

Soil CO2 as a Function of Soil Properties and Tillage Systems on Loamy Soil in Lithuania

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3630 - 3630

Published: April 17, 2025

Investigations of CO2 emissions in the context different tillage systems are relevant not only for studying effects climate change but also evaluating sustainability soil management. To better understand influence physico-chemical properties on emissions, an experiment was conducted to measure direct and indirect these efflux. Soil efflux is measured using a closed chamber method (LI-COR LI-8100A) under various two textures. Our research revealed that temperature, water content, organic carbon, total nitrogen, available phosphorus pH significantly affected soil–atmosphere exchange rate. CO2, volumetric content temperature were higher loam than sandy soil. 8.6% lower conventional reduced no tillage. Total nitrogen carbon contents dependent decreased from agrochemical such as SOC, phosphorus, potassium evaluated The results this valuable contributions knowledge management relation morainic loamy

Long-Term Effect of Tillage Systems on the Planosol Physical Properties, CO2 Emissions and Spring Barley Productivity

Published: June 13, 2024

Soil tillage intensity influences the distribution of nutrients, and soil’s physical me-chanical properties, as well gas flows. The impact reduced on these indices in spring barley cultivation is still insufficient requires more analysis a global scale. This study was carried out at Vytautas Magnus University, Agriculture Academy (Lithu-ania) 2022–2023. aim investigation to determine effect systems soil temperature, moisture content, CO2 respiration concentration limited by semi-humid subarctic climate. Based long-term experiment, five were tested: deep shallow mold-board ploughing, cultivation-chiselling, no-tillage. Shallow ploughing technology found be better conserving maintaining higher temperature. Deep had lower content fields most cases increased emissions concentration. results show that direct sowing fields, positive crop density. Direct resulted significantly grain yields years studied.

Physical Attributes of Soil and Productivity in Intercropped Sorghum Grain within No-Tillage Cropping System

Published: July 24, 2024

A favorable physical environment in the soil is necessary and of fundamental importance for growth root development sorghum crop, order to maximize productivity planted crops. In this study we evaluated aspects no-tillage system a grain area intercropped with Urochloa ruziziensis Crotalaria spectabilis off-season (second crop season), based long field experiment. The experimental design was randomized block 4 x factorial arrangement (four cropping systems: sorghum, + ruziziensis, spectabilis, spectabilis; four depths: 0 - 0.10 m, 0.20 0.30 0.40 m). It analyzed attributes that were: Soil Bulk Density (DS), Gravimetric Moisture (GM), Total Porosity (TP), Microporosity (MI), Macroporosity (MA) Resistance Root Penetration (RP). asserts intercropping promising strategy increase productivity. Sorghum combination significantly improves structure by reducing penetration resistance increasing macroporosity, especially at depths greater than m. inclusion enhances moisture retention, while contributes porosity.
