“…However, leaving crop residues on the soil surface moderates soil temperature and can be used by farmers to improve soil temperature conditions for crop growth, especially during warm months (AWAL et al, 2019;STEFANOSKI et al, 2013). In addition to moderating soil temperature, surface residues also mitigate soil erosion rates, enhance soil organic carbon and nutrient concentrations, and increase infiltration rate and volumetric water content at field capacity (ESSER, 2017;HUBBARD;STRICKLAND;PHATAK, 2013;RYKEN et al, 2018;SOUZA et al, 2018).…”

This study aimed to determine how crop residue placement and composition would affect soil water content and temperature during the dry season in the central region of Espírito Santo state, Brazil. A 19-week field study was conducted from April to August 2017. A 2 x 4 factorial study with four replications was implemented using a randomized complete block design. Factors were soil management [conventional tillage (CT) and no soil disturbance (ND)] and residue amendment [maize (Zea mays L.), sunn hemp (Crotalaria juncea L.), a maize-sunn hemp mixture, and a no amendment control]. Soil water content and temperature were measured weekly at predetermined soil depth intervals. Soil water content was higher in ND plots amended with surface residues than under all other treatments in the 0 to 0.05 m depth range. All residue amendments in this range were equally effective in conserving soil water. Surface residues reduced soil temperature by up to 8.4 °C relative to the control in ND plots. Incorporating residue amendments by CT cancelled all temperature-moderating benefits provided by surface residues. These results indicate that surface residues from cereals, legumes, or cereal/legume mixtures are equally effective in conserving soil water and moderating soil temperature during the dry season. Additional research is needed to determine how improved soil environmental conditions, generated by surface residues, would affect nutrient acquisition and crop performance.

“…In Brazil, mulching and hydroseeding are the most‐used strategies. Both aim only to recondition the soil and minimize regular soil losses, while ignoring the effects of the invasion of exotic plant species (de Aquino et al., ; da Silva, Santos, & dos Santos, ; Souza et al., ). Furthermore, the application of hydroseeding and mulch can introduce and spread invasive exotic plant species (Kahmen, Poschlod, & Schreiber, ; Kruse, Bend, & Bierzychudek, ; Ramakrishna, Tam, Wani, & Long, ).…”

Soil erosion and the invasion of exotic plant species are major constraints to achieve sustainable development around the world. Currently, we find few products devoted concomitantly to combatting soil erosion as well as the establishment of unwanted exotic plants. In this paper, we introduce a new product, called herein a bioblanket, that protects the soil and impedes the establishment of exotic plant species. This product is of simple design, and to manufacture it, we use two biodegradable materials: jute tissue and grass wastes. We designed this product to combat soil erosion and the germination and establishment of new, unwanted, invasive plant species. In this paper, we describe our evaluation of how successful this product was in terms of improving the chemical attributes of soil. We also identified the product's potentialities and weaknesses by means of strengths, weaknesses, opportunities, and threats (SWOT) analysis. The bioblanket ameliorated the chemical attributes of the soil, as evidenced especially by the neutralization of acidity (8.5%) and aluminum toxicity (33%), and by an increment in nutrients concentration. We argue that after adequate treatment and management, the residues of plants that are normally considered unwanted materials can be transformed into a raw material to control the propagation of unwanted plant species, and concomitantly control soil erosion while improving the chemical conditions of the soil. The improvement of the soil chemical attributes was one of the main positive effects reported through the SWOT analysis. In addition, the SWOT analysis revealed some features that need improvement in future generations of the product, but we argue that these features do not impede the benefits for the use of the product in its present form.
