“…The intercropping planting pattern can not only increase farmers' income but also has many additional advantages. Therefore, intercropping ecosystems have been extensively used worldwide, including in Germany (Streit et al, 2019), Brazil (Batista et al, 2019), India (Das et al, 2019), Pakistan (Iqbal et al, 2019), and China (Zhou et al, 2019).…”

“…The lower production of GS in the present study as well as CSM was due to the water deficit during the experiment. The dry mass results of forage grasses showed the importance of using forage grasses for straw formation in the dry season, providing physical protection and moisture, contributing to the increase in soil organic matter content (Batista et al 2019).…”

The intercropping of corn with forage grasses increases soil cover and may improve soil structural quality. The objective of the study was to evaluate the soil structural properties and the development of second-crop corn intercropping with forage grasses under no-tillage system. The experiment was carried out in an area of Sítio Santo Antônio, located in the municipality of Borrazópolis, Paraná state, Brazil, on a Red Latosol with a very clayey texture. The experiment consisted of five treatments: corn + Urochloa brizantha cv. Marandu (T1), corn + Urochloa brizantha cv. Piatã (T2), corn + Urochloa brizantha cv. Xaraés (T3), corn + Urochloa ruziziensis (T4), and non-intercropping corn (T5). In the corn crop, the following characteristics were evaluated: plant height, first ear in insertion height, stem diameter, corn yield, dry mass of corn straw mulch, dry mass of grasses shoots and dry mass of grasses root. Dry mass of the aerial part and roots of the grasses were evaluated. In the 0-0.10 and 0.10-0.20-m soil depth, soil physical properties were also determined: tensile strength and friability, stability of aggregates, bulk density and total porosity, and degree of compactness. The treatments of corn in intercropping with grasses showed positive results regarding the stability of aggregates, reduction of bulk density and increase of total porosity in the 0-0.10-m soil depth. The intercropping of corn + U. ruziziensis showed the lowest values of degree of compactness and higher production of dry mass of the aerial part.

“…In terms of nutrient cycling, both the amount of plant residue on the soil surface and the availability and lability of nutrients such as carbon and nitrogen in the soil are strongly influenced by nitrogen fertilization [9]. In addition to this, the high demand for nitrogen from maize and tropical grasses for development and productivity highlights the importance of adequately supplying nitrogen in intercropping systems [8]. However, currently, nitrogen fertilization is only performed in planting rows in maize-tropical grass intercropping systems , either in planting or side-dressing, as recommendations consider grain farming [4,10].…”

“…In recent years, intercropping systems between maize and tropical grasses with no tillage in the autumn-winter season have shown high grain yields and biomass productions in Brazil [8]. Among the tropical grass genera used in these intercropping systems, Urochloa and Megathyrsus showed good soil coverage.…”

In Brazil, grain crops in no-till soybean–maize succession have reduced biodiversity and carbon input into soil. Intercropping is a promising approach to address these problems. This study aimed to evaluate the microbiological quality of soil in conventional and intercropping systems in soybean–maize succession, depending on tropical grass and nitrogen fertilizer uses. The treatments were arranged in a randomized complete block design and a split plot scheme, with four replications. The main plots consisted of the following cropping systems: soybean monoculture–maize monoculture; soybean intercropped with Aruana Guinea grass (Megathyrsus maximum cv. Aruana)–maize intercropped with Aruana Guinea grass; and soybean intercropped with Congo grass (Urochloa ruziziensis cv. Comun)–maize intercropped with Congo grass. The subplots consisted of nitrogen rates (0, 50, 100, and 150 kg ha−1) applied as side-dressing in rows of maize and tropical grass in the autumn–winter season. Our results showed that maize or soybean intercropped with tropical grasses and adequate nitrogen rates favored the entry of microbial carbon and nitrogen, stimulated enzymatic activity, and reduced C-CO2 loss. However, the excess nitrogen supply can nullify the benefits of the intercropping systems. We concluded that the intercropping systems can improve soil microbiological quality in a short time with adequate nitrogen supply.
