Abstract Double-cropping winter rye cover crops (CC) with soybean in the North Central US could help global effort to sustainably intensify agriculture. Studies addressing management of these systems are limited. Therefore, a field study was conducted from 2017 2019 Iowa, evaluate CC biomass production, aboveground N accumulation, estimated economics, within-field energy balance and greenhouse ...

We investigated potential use of prairie as a Midwestern cellulosic feedstock by conducting a 9 ha side-by-side comparison of maizeand prairie-based systems on fertile soils in Boone County Iowa, USA. Investigated systems were: maize-soybean rotation grown for grain only, continuous maize grown for grain and stover both with and without a winter rye cover crop, and a 31-species reconstructed pr...

The adoption rate of winter cover crops (WCCs) as an effective conservation management practice to help reduce agricultural nutrient loads in the Chesapeake Bay (CB) is increasing. However, the WCC potential for water quality improvement has not been fully realized at the watershed scale. This study was conducted to evaluate the long-term impact of WCCs on hydrology and NO3-N loads in two adjac...

Cover crops (CC) provide numerous ecosystem services such as improving soil health, reducing nutrient loss, increasing productivity, and mitigating greenhouse gas emission. However, adoption of CC has been hindered by perceived negative impacts on main crop productivity additional production costs. This is partly attributed to the gap in current state knowledge its interaction with under differ...

Abstract Winter-hardy small grains offer an opportunity to improve soil health as a cover crop, and they can also be used forage source for cattle. differ in the time needed reach various maturity stages. Species selection may impact yield nutritive value. A two-year study was conducted eastern Nebraska determine effect of species on value winter-hardy silage. Three were evaluated; cereal rye, ...

Winter rye, with all its advantages (adaptability, stress resistance, increased productivity), cannot compete other grain crops, and the reason is quality to a greater extent. Solution of issue possible when cultivating rye varieties low content water-soluble pentosans in grain. In Western Siberia, winter has traditionally been considered leading crop, which efficiently uses environmental resou...

It is a fact that crops growth conditions vary greatly in the same field. Provisionally actual growth conditions are made up of many components, i.e. variation of natural conditions (climate & soil), results of effect of machinery on soil ( soil compaction) and unfavourable conditions for plant growing. In Estonia rather widely used ATV are causing remarkable damage to landscapes. All collected...

To investigate the different responses of crops to drought stress under field conditions Central European Climate for selected crop rotations, a experiment was conducted at test site in Czech Republic from 2014 2021. Depending on crop, rainout shelters were placed late spring and early summer study effects final stages development. Due these associated lower water availability during summer, re...

Cover crop (CC) species selection can contribute to reducing soil penetration resistance (brassica species), improved nitrogen (N) cycling (legume and suppression of weeds (grass species). However, one the main concerns about including CCs in water-limited environments is water use consequences subsequent crops. To determine effects individual CC under environments, we evaluated fall spring bio...
