“…Despite the high potential for agriculture, part of its area must be kept as a reserve for the protection of the biodiversity of these environments. Fidalski (2015) corroborates that this soil does not have porosity limitations for soybean and forage cultivation. França et al (2019) reinforces that the indication of use is dependent on the level of management, and the more technified the production, the greater the alternatives for using the area, also taking into account the type of soil.…”

This study aimed to develop a diagnosis of land use suitability, growth prospects and milk production intensification in a family farm located in Conceição do Tocantins, Tocantins, Brazil. Data were obtained through interviews with employees and residents, cooperative members, analysis of productive activities and sources of income. To understand the milk production intensification, an experiment was carried out with the division of an area of 1 ha into 3 paddocks and pasture management. For soil aptitude characterization, vector data provided by Seplan were used. The division of the area into paddocks and pasture management allowed an increase in the animal load of 3 AUha-1year-1 and 48% in the daily milk production in the winter and 32% in the summer. In view of the results, it could be concluded that well-formed areas, rest and occupation period with grass reached animal load of 10 AUha-1year-1. Thus, the possibilities of agroecological intensification of pastures were promising and productive; however, investments were high. For professionals interested in these changes, it is necessary to invest in quality paddocks and cattle, in addition to professional training.

“…The stocking rate, shoot dry matter of palisade grass, BIR, and VESS for the recommended grazing height of 30 cm are essential in integrated agricultural production systems. Thus, the activities must be planned and executed aiming at the synergy between plant and animal production without compromising soil quality (Balbinot, Moraes, Veiga, Pelissari, & Dieckow, 2009;Carvalho et al, 2014;Fidalski, 2015a;Carvalho et al, 2018).…”

Grazing intensity on palisade grass as a function of grazing height in a crop-livestock integration (CLI) system alters the structural soil quality and water infiltration. This study aimed to verify the magnitude of the stocking rate and shoot and root dry matter of palisade grass at the end of the fifth cattle grazing period of an experiment in the CLI system on the visual evaluation of soil structure (VESS), soil-water infiltration rate, and basic infiltration rate (BIR) as a function of grazing heights on Urochloa brizantha cv. MG 5 Vitória in the northwestern Paraná State, Brazil. The experimental design consisted of randomized blocks with three replications and 1-ha experimental plots on an Oxisol. Four treatments with grazing heights of 10, 20, 30, and 40 cm were used in the CLI system, controlled with variable stocking rates of Purunã cattle in the autumn/winter season on Urochloa brizantha cv. MG 5 Vitória in succession to soybean in the summer. The maximum soil water infiltration was stabilized at 30 cm of grazing height of the palisade grass under continuous grazing in the CLI system. The increase in the stocking rate decreased the shoot dry matter of palisade grass, soil water infiltration, and structural soil quality.

“…En general, si bien resultados como de Demuner et al (2013), Silva y Fernández (2014), Fidalski (2015 y no encontraron diferencias significativas entre los sistemas que evaluaron sobre la Da y Rp; los resultados, se explican considerando que tanto la CO como el CA fueron tratados con herbicida desde su establecimiento (12 años) y en los suelos de coca hay varios factores que afectan negativamente los indicadores físicos del suelo, entre ellos: el aporte de residuos al suelo (la hoja es cosechada periódicamente), queda descubierta por largos periodos y la superficie queda expuesta a la erosión hídrica; en consecuencia se genera perdida de los horizontes superficiales del suelo y alteraciones en la estructura. Por tanto, los resultados más desfavorables del suelo con coca son coherentes con las referencias citadas.…”

La investigación evaluó el impacto del manejo convencional de los cultivos de Erythroxylum coca, Theobroma cacao L. y bosque como referencia, sobre indicadores físicos y químicos del suelo, en Padre Abad región Ucayali-Perú. Se utilizó un diseño completamente aleatorizado, los tratamientos lo constituyen los sistemas de manejo convencional de coca (CO), cacao (CA) y bosque secundario (BS) como referencia; se evaluaron indicadores físicos como densidad aparente (DA) y resistencia a la penetrabilidad (RP) en estratos de 0,00 a 0,10 m (DA10 y RP10) y 0,10 a 0,20 m (DA20 y RP20) y los indicadores químicos pH, materia orgánica (MO), fosforo (P), potasio (K+), calcio (Ca2+), magnesio (Mg2+), aluminio (Al3+), saturación de aluminio (%SAl) y la acidez cambiable (%AC). Los resultados muestran diferencias significativas en indicadores físicos DA10, DA20, RP10 y RP20 y en los indicadores químicos pH, MO, K+, Ca2+, Al3+, AC y SAl. Se concluye, que el manejo convencional de coca afecta severamente los indicadores físicos DA y RP en ambos estratos evaluados y afecta negativamente sobre indicadores químicos, disminuyendo los niveles medios de pH, MO, P, K+, Ca2+, Mg2+ y los valores más alto en resistencia a la penetrabilidad superficial, aluminio intercambiable y acidez cambiable, en comparación al bosque.
