“…Therefore, CF mulching with a thickness of 7 cm had the most significant effect on the vertical distribution of soil water, and was suitable for mulching a large area to improve the water content of different soil layers. This is consistent with the results of Zhang et al [36]: Under the cover of the CF, the soil exhibited relatively high moisture content at different depths. This is attributable to the following factors: on the one hand, the CF physically blocks sunshine and wind, reducing the evaporation of soil moisture; on the other hand, the cold and hot airs meet inside the CF, making it easy for soil moisture to condense into water droplets.…”

Organic mulch can improve the moisture, chemical composition, dust, and dust suppression of soil, and beautify the environment. In view of the rapid evaporation rate and serious loss of soil water in tropical areas, this paper explored the effect of organic mulch materials with different thickness on the increase of soil water retention rate and the improvement of soil water loss caused by evaporation. Rubberwood sawdust (RWS), rubberwood bark (RWB), coconut fiber (CF), and Mulch (MC) were selected as the mulching materials. Field experiment and laboratory experiment were performed, and soil-moisture content and temperature were continuously monitored. However, from the daily measurement of water content at constant conditions (29°C ± 0.2°C, 74% ± 1% air RH) in the laboratory experiment, the results of variance analysis (ANOVA) showed that there was no significant difference between the soil-water content of covered samples and bare soil (P > 0.05). In the field experiments, the analysis of variance indicated significant differences in the soil-moisture content owing to the effect of the covering material (P < 0.01). Mulching increased the soil-moisture content with smaller fluctuations in the deep soil compared with bare soil. The most stable soil-moisture content were achieved by RWS, RWB, CF, and MC, with thicknesses of 5, 3, 7, and 5 cm, respectively, compared with bare soil, and the average water contents of the 0-40 cm soil layer was 0.58%, 0.01%, 0.82%, and 0.93%, respectively. Vertically, the intensity of the change in soil moisture decreased gradually with increasing depth, and was more stable than that of bare soil and other treatments. Among them, the difference in water content between the adjacent gradient soil layers (the soil layers are graded every 10 cm in depth) M 3-7 (0.011 ± 0.004) was the smallest. It can be concluded that CF mulching materials with a thickness of 7 cm would be preferable when selecting mulching materials for controlling soil moisture in tropical cities.

Esse tipo de prática agronômica visa diminuir a perda de água para a atmosfera e a eficiência dos sistemas de cultivo, principalmente em regiões áridas e semiáridas, onde ocorre demandas evapotranspirativas altas (Quintanilla-Tornel et al, 2016;Alves et al, 2018;Zhang et al, 2021).…”

“…Buscando-se aumentar a eficiência na utilização da água aplicada via irrigação, a adição de cobertura morta sobre o solo permite a persistência da água no solo por mais tempo. Assim, a cultura tem maior desempenho agronômico e com essa cobertura vegetal agregada ao solo, pode melhorar as condições químicas, físicas e microbiológicas do solo, tornando as condições de cultivos mais propicias para as condições semiáridas (Alves et al, 2018;Zhang et al, 2021;Bis et al, 2022;Liu et l., 2022).…”

The cultivation of adapted species (e.g., forage cactus, sorghum, millet, etc.) can provide greater forage productivity in arid and semi-arid environments. However, due to water limitations in the region, it is important to use irrigation, when well managed, it allows for greater production and provides opportunities for the insertion of intercropping crops even in dry periods. Thus, this review aimed to survey the main indices of biological efficiency, competitive ability and economic benefit in different forage species and crops, as well as the use of resilient practices that seek to increase the efficiency and sustainability of forage production in an environment semi-arid. Scientific articles in Portuguese and English from the last ten years were used, using the following platforms: Google Academic, Scielo, ScienceDirect, Scopus, and Web of Science, paying attention to the quality and timeliness of the literature cited. The use of resilient agricultural practices such as irrigation, planting of adapted species, straw mulch and intercropping are of great importance for productive units in the Brazilian semi-arid region. As well as the use of indices of biological efficiency, competitive ability and economic return, which are capable of helping to determine the best configurations of intercropping crops, providing greater reliability and profitability of the agricultural chain in semi-arid regions.

“…A cobertura orgânica sobre o solo tem capacidade de modificar as estruturas físicas, químicas e biológicas do agroecossistema da área cultivada (Figura 10), dentre elas: diminuir a incidência da radiação direta sobre o solo, reduzindo a temperatura do mesmo; aumentar a retenção de água; reduzir a erosão e melhorar a fertilidade do solo através de sua decomposição, aumentando a relação C/N (Alves et al, 2018;Zhang et al, 2021). Também é capaz de diminuir a infestação de parasitas maléficos, assim como aumentar a diversidade de microrganismos benéficos, o que possibilita uma maior reciclagem de nutrientes no solo, favorecendo um maior aproveitamento pela planta e, consequentemente, potencializar os rendimentos (Aquino et al, 2015;Mendonça et al, 2019;Bamber et al, 2020).…”

The low forage productivity in the Brazilian semi-arid is linked to water scarcity and climatic conditions, these abiotic disturbances affect the development of livestock and the local economy. Seeking to circumvent the situation, the use of forage species adapted to climatic conditions is of paramount importance, such as forage cactus, a crop rich in nutrients, much appreciated by animals, but lacking in fiber and protein, making it necessary to use other forage plants like sorghum, millet, pigeon pea and forage sunflower, both species have high levels of fiber and protein, and with this, they complement each other and enable the production of more balanced diets for herds. However, the higher yield of crops is observed with the implementation of resilient practices such as irrigation, adoption of mulch, intercropping, which promotes more sustainable systems with high forage potential. In this review, the objective was to evaluate the use of different agronomic practices to increase the productivity and sustainability of forage cactus crops and crops of regional appeal to the Brazilian semi-arid region. It is concluded that the sustainable intensification of agricultural crops, through complementary irrigation, mulch, intercropping with forage cactus, and plant species adapted to the Brazilian semi-arid region, can promote an increase in forage production without adverse effects on ecosystems.
