“…[47] reported contradicting results as legume cover crops (white clover and orchard grass) in their study decreased pH levels, which was attributed to the secretion of organic acids and protons by the legume roots. Soil acidity is a key constraint associated with poor root health and nutrient availability [49]. Under acidic conditions, nutrients such as P form insoluble complexes with cations, rendering them unavailable for plant uptake [50].…”

Vicia sativa and Vicia villosa are nitrogen (N) fixing legumes commonly used as forage and cover crops due to their ability to enhance N fixation, soil N contributions, and enzyme activities in nutrient-deficient soils. Using V. sativa and V. villosa as cover crops can potentially improve nutrient cycling in nutrient-deficient sugarcane plantations owned by small-scale growers (SSGs) in KwaZulu-Natal, South Africa. This study investigated the chemical and biological inputs of V. sativa and V. villosa in nutrient-deficient sugarcane plantation soils. The nutrient concentration, N and phosphorus (P) cycling bacteria, and extracellular enzyme activities of soils collected from five small-scale sugarcane plantations were determined pre-planting and post-V. sativa and V. villosa harvest. Post-V. sativa and V. villosa soils had higher pH levels than pre-planting soils across all plantation soils. The number of plant growth-promoting rhizobacteria (PGPR) isolated from soils post-V. sativa and V. villosa harvest increased across all plantation soils. The Arthrobacter, Burkholderia and Paraburkholderia Pseudomonas were the most dominant genera isolated from post-harvest soils. The number of P-solubilising bacteria increased, increasing acid phosphatase activities. The findings of this study reveal that V. sativa and V. villosa increase PGPR, pH and enzyme activities in soils, making them sustainable options as cover crops for nutrient-deficient sugarcane plantation soils owned by SSGs.

“…The root length included the entire root extension, with higher averages being observed in plants irrigated with TSE (20 cm) compared to TSE and SRW at a depth of 40 cm. This indicates greater root branching and extension, ensuring improved soil use and, consequently, better water and nutrient absorption [66][67][68]. Well-developed root systems are fundamental for sugarcane adaptation to different environmental conditions, improving survival [69,70].…”

Studies on the development of the root system can provide important information about responses to different management strategies, such as the use of lower quality water, also evaluating the interaction between plants and the physical properties of the soil. This study tested the hypothesis that irrigation with treated sewage effluent (TSE) supplies the water needs of sugarcane plants, increasing root growth and improving the physical properties of the soil. We evaluated the effects of subsurface dripping with TSE or surface reservoir water (SRW) on the root development of first ratoon cane (Saccharum officinarum L.) and the physical properties of dystrophic red latosol. Irrigation treatments were applied at 20 and 40 cm and soil properties were evaluated at soil depth layers of 0–20, 20–40, 40–60, and 60–80 cm. We verified that under irrigation with TSE and SRW, shallower soil layers present better porosity, soil aggregation, and aggregate stability conditions, parameters that improve the root system development and plant growth. On the other hand, deeper soil layers have lower macroporosity and higher total clay volume, indicating the possibility of compaction and greater limitations for sugarcane root growth. These results are important for understanding soil quality and provide significant information for agricultural management and for the implementation of sustainable soil conservation practices. This study shows the efficiency of TSE as an alternative water source for sugarcane crops.
