“…Previous research suggests that specific SOC fractions, as opposed to the entire SOC pool probably have a greater influence on soil microbial community, nutrient cycling and availability, and aggregation, making them a more accurate and trustworthy indicator of changes carried by management practices and environmental factors. POC (Cui et al, 2014 ) and MBC (Li et al, 2019a ) are two soil C fractionation approaches that have been successfully introduced and verified using field data (Culman et al, 2012 ). Each SOC fraction metric's utility and sensitivity remain poorly understood, and it is unclear how different climatic, edaphic and field management conditions might interact with or affect these variables.…”

Global climate change stress has greatly influenced agricultural crop production which leads to the global problems such as food security. To cope with global climate change, nature based solutions (NBS) are desirable because these lead to improve our environment. Environmental stresses such as drought and salinity are big soil problems and can be eradicated by increasing soil organic matter which is directly related to soil organic carbon (SOC). SOC is one of the key components of the worldwide carbon (C) cycle. Different types of land use patterns have shown significant impacts on SOC stocks. However, their effects on the various SOC fractions are not well-understood at the global level which make it difficult to predict how SOC changes over time. We aim to investigate changes in various SOC fractions, including mineral associated organic carbon (MAOC), mineral associated organic matter (MAOM), soil organic carbon (SOC), easily oxidized organic carbon (EOC), microbial biomass carbon (MBC) and particulate organic carbon (POC) under various types of land use patterns (NBS), including cropping pattern, residue management, conservation tillages such as no tillage (NT) and reduced tillage (RT) using data from 97 studies on a global scale. The results showed that NT overall increased MAOC, MAOM, SOC, MBC, EOC and POC by 16.2%, 26.8%, 24.1%, 16.2%, 27.9% and 33.2% (P < 0.05) compared to CT. No tillage with residue retention (NTR) increased MAOC, MAOM, SOC, MBC, EOC and POC by 38.0%, 29.9%, 47.5%, 33.1%, 35.7% and 49.0%, respectively, compared to CT (P < 0.05). RT overall increased MAOC, MAOM, SOC, MBC, EOC and POC by 36.8%, 14.1%, 25.8%, 25.9, 18.7% and 16.6% (P < 0.05) compared to CT. Reduced tillage with residue retention (RTR) increased MAOM, SOC and POC by 14.2%, 36.2% and 30.7%, respectively, compared to CT (P < 0.05). Multiple cropping increased MAOC, MBC and EOC by 14.1%, 39.8% and 21.5%, respectively, compared to mono cropping (P < 0.05). The response ratios of SOC fractions (MAOC, MAOM, SOC, MBC, EOC and POC) under NT and RT were mostly influenced by NBS such as residue management, cropping pattern along with soil depth, mean annual precipitation, mean annual temperature and soil texture. Our findings imply that when assessing the effects of conservation tillage methods on SOC sequestration, SOC fractions especially those taking part in driving soil biological activities, should be taken into account rather than total SOC. We conclude that conservation tillages under multiple cropping systems and with retention of crop residues enhance soil carbon sequestration as compared to CT in varying edaphic and climatic conditions of the world.

“…While a considerable proportion of the livestock industry in this region depends on grain‐based rations to support the confined beef and dairy feeding operations (Lauriault and Kirksey, 2004), forage production based on alfalfa and other annual and perennial forage is also necessary to provide more sufficient dietary fiber and other essential nutrients that are not provided by grain. However, land dedicated to these highly productive staple forage crops is being converted to less productive pastures due to increasingly limited water for irrigation (Lauriault and Kirksey, 2004; Environmental Protection Agency (EPA)., 2013; Cui et al, 2014; Brauer et al, 2017), especially in the semiarid Southern High Plains. The declining water resources in the Southern High Plains prompt a need for effective water management practices to sustain forage production to meet the growing demand for livestock industries (Lauriault and Kirksey, 2004; Lauriault et al, 2006).…”

Irrigation and Drainage

Managing water in alfalfa (Medicago sativa L.) production is crucial for sustaining the limited surface and groundwater resources. A 3-year study in eastern New Mexico, USA, compared nine irrigation strategies that included various combinations of in-season irrigations for six harvests (1-2-3-4-5-6, 1-2-3-4-5, 1-2-3-5, 1-2-3, 2-3-5, 1-2-5, 1-5, and 2-3) plus unirrigated control (none) to evaluate the dry matter (DM) yield production capability and irrigation efficiency. The number in each treatment structure represents irrigation provided for each cutting. For example, number '1' represents irrigation provided for the first cutting; number '2' represents irrigation provided for the second cutting, and so on. The results suggested that terminating irrigation for the last harvest (1-2-3-4-5), equivalent to 96 mm water saving, had no significant negative impact on annual DM yield of established alfalfa compared to season-long full irrigation (1-2-3-4-5-6) (14.4 vs 13.3 t ha −1 ; P > 0.05) during the 3-year study period. Irrigation water productivity was doubled when alfalfa was irrigated during the first three harvests (1-2-3), compared to 1-2-3-4-5-6 (0.050 vs 0.027 t ha −1 mm −1). The second and third harvests provided the greatest DM yields in alfalfa. The DM yields declined drastically after the third harvest, with the exception of the third year. Therefore, irrigating alfalfa early in the season during the initial three harvests is an important strategy when water is limited.

“…Ruiz et al (1991) and Castillo et al (1991) reported that animal performance did not increase when legumes exceeded 50% of the grass-legume system. Interseeding alfalfa and yellow sweetclover (Melilotus officinalis L.) into the base OWB pasture can further add to the effectiveness of an alfalfa protein bank (Ruiz et al, 2005;Cui et al, 2014). The result was a more stable pasture system with higher legume population and increased biomass production through more rooting points (nodes) and lower weed pressure.…”

“…Crude protein (CP) is often the limiting factor in improving performance of steers grazing these warm‐season pastures (Minson, 1990; Allen et al, 2005). Not only do legumes reduce or eliminate nitrogen (N) fertilizer requirements through biological N fixation, they also improve forage nutritive value by increasing CP and dry matter (DM) digestibility (Entz et al, 2002; Cui et al, 2014). Alfalfa ( Medicago sativa L.) is the most important forage legume produced in the western United States, primarily as a source of high‐quality hay and silage for dairy cattle (Evers, 2011; Butler et al, 2012).…”

The imminent decline of the Ogallala Aquifer is encouraging producers in the Southern High Plains (SHP) to seek innovative alternatives to safeguard against dramatic losses of income when pumping capacity is insufficient for irrigated crops. Previous research demonstrated the success of perennial forage grasses in this region, but crude protein (CP) was the limiting factor in improving performance of grazing beef (Bos taurus L.) steers. Possible solutions include integrating legumes into existing warm‐season grass pastures and managing small areas of alfalfa (Medicago sativa L.) as a protein bank where irrigation resources can be concentrated. The objective of this research was to compare animal performance in a grass‐legume pasture system employing regionally novel forage combinations and grazing techniques to a grass‐only system in the water‐limited SHP. Three years of research concluded that inclusion of legumes increased CP (P < 0.01) and increased digestibility measures of forages in the grass‐legume system. Longer, less frequent rotations into the protein bank resulted in higher average daily gains in Years 2 and 3 (P < 0.05) compared with Year 1 of grass‐legume. This translated to higher seasonal liveweight gain per hectare in the grass‐legume system in each trial year (P < 0.01). The forage‐livestock systems created in this research will serve as alternatives for producers transitioning from irrigated row crops into more resource‐sustaining systems.
