Available in PDF, EPUB and Kindle. Book excerpt: Cover Crops and Soil Ecosystem Services A comprehensive resource on cover crops and their role in soil ecosystems Cover crops are a reemerging strategy to improve and maintain the services that soils provide. They can have an enormous affect on agricultural outcomes, preventing soil erosion, restoring vital soil nutrients, sequestering C from the atmosphere, and more. The successful management and use of cover crops is therefore critical to ensure soil ecosystem services are maintained or improved not only to meet our demands for food, fuel, fiber, and feed but also to reduce pollution and improve the soil. Cover Crops and Soil Ecosystem Services provides a heavily researched and highly readable introduction to cover crops and their role in soil ecosystems. It ranges from a detailed discussion of cover crop biomass production to a thorough treatment of soil ecosystems and their vulnerabilities. The result is an essential guide to a critical area of agricultural science. Cover Crops and Soil Ecosystem Services readers will also find: Detailed treatment of cover crop biomass production, soil erosion, greenhouse gas fluxes, nitrate leaching, soil C sequestration, and more Discussion of emerging issues, including extreme weather events and the economics of cover crop farming Wide-ranging summaries of interdisciplinary soil and cover crop research Cover Crops and Soil Ecosystem Services is a useful reference for students and researchers at all levels of study relating to cover crop agriculture.

Available in PDF, EPUB and Kindle. Book excerpt: Management intensive grazing of cover crops (MIGCC) in continuous no-tillage systems is an opportunity to procure mutual benefits of cover crops for improving soil health and providing forage to livestock. However, soil compaction by grazing animals could also have negative effects on soil structure. Therefore, the research studied impact of management intensive grazing of cover crops on soil physical and biological properties as well as forage production and economic returns. The research was conducted on four farms in southcentral Pennsylvania between 2019 and 2021. The comparison was between the grazed and ungrazed cover crop after small grain or corn silage harvest and between double-cropped soybeans and grazed cover crop after small grain harvest. After small grain or corn silage harvest, cover crops were planted and grazed, and cattle were moved daily with a target of leaving roughly 50% of cover crop biomass for soil protection and soil health management. The first experiment used a randomized full block design with a factorial arrangement of grazing treatment (ungrazed, recently grazed, and grazed 2 weeks earlier) and season (spring or fall) with four farms representing four replication per treatment. Bulk density, aggregate stability, field saturated hydraulic conductivity, soil CO2 burst, organic matter content, and permanganate oxidizable carbon were not significantly impacted by grazing in spring or fall. In the fall, cover crop grazing produced 1916-3746 kg ha-1 forage dry matter, and in the spring, 1425-4349 kg ha-1 forage dry matter. Farmers managed to leave an average of 1534-6717 kg ha-1 of total cover crop biomass (ranging from 47-73 percent) for soil function and protection. In spring 2020/2021, net revenue from grazing cover crops varied from $82 ha-1 to $566 ha-1, and in fall 2019/2020/2021, net revenue ranged from $481 ha-1 to $359 ha-1. In the second experiment, the impacts of grazed cover crops and soybeans on soil health and economic returns were compared using a completely randomized design with a factorial arrangement of treatments (grazed cover crop versus soybean) and years (2019, 2020, and 2021) on two farms, Franklin 1 and Adams 1. For Franklin 1, findings indicated greater field saturated hydraulic conductivity and soil organic matter content in grazed cover crop field than full-season soybean in 2019 and double-cropped soybean in 2021, while no effect was revealed on soil CO2 burst. In 2019, full-season soybeans (94%) outperformed grazed cover crops (85%) in terms of aggregate stability, with no difference between treatments in 2020 and 2021. In 2021, the bulk density of the grazed cover crop was lower than in 2020 and 2019. Similarly, the bulk density of soybean fields in 2021 was lower than in 2019. At Adams 1, when compared to double crop soybean, soil under grazed cover crops had higher permanganate oxidizable carbon in 2021 and enhanced structural stability in 2020 and 2021. Between treatments in 2020 and 2021, no significant differences in bulk density, field saturated hydraulic conductivity, soil CO2 burst, or organic matter content were observed at Adams 1. In 2020 and 2021, partial budget analysis revealed a net positive return of $523.13 ha--1 and $103.38 ha--1 for Adams 1. In 2020 and 2021, however, Franklin 1 had a net return of -$250.40 ha--1 and -$93.28 ha--1. For Adams 1, a complete soybean failure rendered management intense grazing of cover crops more profitable than a double crop soybean. Double crop soybean failure is common on droughty soils or during years with extreme weather like drought or early frost, making grazed cover crops a less risky alternative to double crop soybeans after small grain harvest. The results so far indicate that grazed cover crop results in better soil health and provides farmers a reduced risk compared with double crop soybean, especially on marginal soils. The research suggests that under continuous no-tillage systems, grazing cover crops using management intensive practices can provide additional feed and income to the farmer without detrimental effect on soil health, thereby increasing the motivation to adopt cover crops and their derived conservation benefits.

Download or read book Short Term Effects of Annual Ryegrass Red Clover and Hairy Vetch Cover Crops on Various Indicators of Soil Health written by Breanna Stout and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's population has passed 7 billion and is expected grow to more alarming numbers by the year 2050. The increase in human life on the planet ushers the need to responsibly and sustainably grow more food. In order to meet the demand necessary, it is crucial that soil remains healthy and crop yields continue to increase in efficiency. Irresponsible or ill-informed practices can lead to depleted resources and degradation of fertile soils that may limit a producers' ability to sustainably grow food. Cover crops are a tool that can be used to address issues the modern producer may face. Cover crops have been shown to increase cash crop productivity, improve soil health by improving soil physical and chemical properties as well as providing protection from soil erosion runoff or nutrient leaching. A study was conducted in 2014 to examine the short term effects associated with cover cropping systems. The effects of ryegrass, red clover and a cover crop cocktail (mixture of ryegrass, red clover and hairy vetch) compared to bare tilled and bare control plots were studied. The five treatments were replicated three times in a completely randomized study and analyzed. Soil physical health indicators such as bulk density and porosity were calculated. Soil and cover crop nutrient use, as well as, soil moisture content data was collected and analyzed using excel and ANOVA statistical procedures. In the short term, the study found that there was only statistically significant differences between cover cropping regimens, tilled and control plots in regards to biomass production and biomass nutrient concentrations ([alpha]=0.05). The cocktail mix provided more biomass, N and P than the ryegrass and clover plots alone. Observable differences in cover crop volumetric soil moisture and water used between plots demonstrated that cover crops utilize soil moisture in the short term, which must be considered in areas experiencing water stress. Although more long-term data is needed to truly quantify how cover crops effect various aspects of soil health, this study demonstrated how cover crops have the potential for providing numerous benefits such as increased erosion control, lower reliance on anthropogenically created nutrients and the reduction of weeds. Overall the benefits associated with cover crops are still being researched and while adoption of cover cropping systems has been slow, a push towards agricultural sustainability while increasing food production will increase the amount of producers utilizing cover crops in the coming years.

Download or read book Sustainable Intensification of Crop Production written by P. Parvatha Reddy and published by Springer. This book was released on 2016-11-17 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines a new paradigm, Sustainable Intensification of Crop Production (SICP), which aims to produce more from the same area of land by increasing efficiency, reducing waste, conserving resources, reducing negative impacts on the environment and enhancing the provision of ecosystem services. The use of ecologically based management strategies can increase the sustainability of agricultural production while reducing off-site consequences. The book also highlights the underlying principles and outlines some of the key management practices and technologies – such as minimum soil disturbance; permanent organic soil covers; species diversification; selection of suitable cultivars, planting time, age and spacing; balanced plant nutrition; agro-ecological pest management; efficient water management; careful management of farm machinery; and integrated crop-livestock production – required to implement SICP. The green revolution (by using high-yielding crop varieties, mono-cropping, fertilization, irrigation, and pesticides) has led to enormous gains in food production and improved world food security. In many countries, however, intensive crop production has had negative impacts on production, ecosystems and the larger environment, putting future productivity at risk. In order to meet the projected demands of a growing population expected to exceed 9 billion by 2050, farmers in the developing world must double food production, a challenge complicated by the effects of climate change and growing competition for land, water and energy. This book will be of immense value to all members of the scientific community involved in teaching, research and extension activities concerning sustainable intensification. The material can be used for teaching post-graduate courses, or as a useful reference guide for policy makers.
