For maximizing water retention and attaining high yields, transplanting into puddled soil (TPR) is often considered the optimal method of rice ( Orzya sativa L.) establishment. Alternative management techniques like direct seeding (DSR) and deep tillage have been proposed as mechanisms to improve soil physical properti... | Direct-seeded flooded rice (Oryza sativa L.) culture is becoming an increasingly popular alternative to transplanting in some regions of Asia.

To simulate the elements of microclimate, Crop Microclimate Simulation Model of Goudriaan (1977) was applied. The air temperature and humidity w... | eng_Latn | 9,384 |
Long-term crop rotation trials were designed to assess sustainability of alternatives to traditional fallow and monocropping. The trial described here (6 years) involved wheat (Triticum aestivum L.) in rotation with lentil (Lens culinaris L.), forage vetch (Vicia sativa), pasture medic (Medicago spp.), fallow and water... | In this study, we examined the effect of five years of organic farming on soil parameters of a dryland Mediterranean agroecosystem. The study involved a four-course rotation: barley/common vetch/oats/bitter vetch, with incorporation of crop residues into the soil, no fertilization, shallow tillage, and variable sowing ... | Berzelius failed to make use of Faraday's electrochemical laws in his laborious determination of equivalent weights. | eng_Latn | 9,385 |
The type of conservation-tillage management employed could impact surface-soil properties, which could subsequently affect relationships between soil and water quality, as well as with soil C sequestration and greenhouse gas emissions. We determined soil bulk density, organic C and N fractions, plant-available N, and e... | Tillage practices can redistribute the soil profiles, and thus affects soil organic carbon (SOC), and its storage. The stratification ratio (SR) can be an indicator of soil quality. This study was conducted to determine tillage effects on the profile distribution of certain soil properties in winter wheat (Triticum aes... | We prove that groups acting geometrically on delta-quasiconvex spaces contain no essential Baumslag-Solitar quotients as subgroups.
