Efecto antrópico en propiedades del suelo en sistemas de producción agrícola en la granja Santa Inés

Soil is the main element for the health of agroecosystems; however, agricultural activities have altered the properties of the soil, affecting the quality of the non-renewable natural resource. The objective of the work was to determine the anthropogenic effect of agricultural management on the physical, chemical, and biological properties of the soil in production systems of the Santa Inés farm. For this, permanent sampling points were randomly selected in five agroecosystems (cocoa, banana, corn, pastures, and forest) belonging to the Santa Inés farm. The anthropogenic effect in agriculture has significantly transformed the properties of the soil, caused by the intensive use of agricultural tillage, fertilizers, and pesticides which have caused notable changes in apparent density, porosity, sand content, clay, and nutrients. The modifications that occurred in the physical, chemical, and biological properties of the Inceptisol soil reflect the direct influence of agricultural practices on soil degradation and its ability to maintain sustainable crops.

Optimizing oil palm farming: Soil quality, fertilization and agro-environmental performance

The essential role of fertilization in the management of oil palm plantations cannot be overstated, with the understanding that effective strategies must be fine-tuned to accommodate the diversity of soil types present. The nuanced response of oil palm to fertilization under different soil conditions underscores the critical nature of this research. This study investigates the relationship between oil palm farming practices and agro-environmental performance of plantations. This research aims to understand the complex mechanisms influencing plantation productivity. Five agronomic field experiments were carried out on various soil types (Podzol, Inceptisol, Peat) during 2022. These experiments involved various types of soil and used different plant materials in a total land area of 33 hectares. The results of the peat soil trials revealed a positive effect of RP fertilizer on leaf phosphorus (P) content and a visible gradient in potassium (K) content with different doses of KCl. Average plantation yields peaked in 2022, showing the best yields ever recorded. On the contrary, experiments in podzolic soils showed that oil palm responded better to organic fertilizers than to mineral fertilizers in podzolic soils. The inceptisol soil revealed a significant increase in leaf potassium (K) content with KCl dose, confirming the positive effect of fresh oil palm empty fruit bunches (EFB) on potassium levels. In particular, EFB acts as a good K fertilizer, positively influencing the K content but negatively affecting the calcium content (Ca) due to K/Ca antagonism. These findings emphasize the need for diversified agricultural strategies to optimize oil palm cultivation, increase productivity, and reduce dependence on external input.

Application of Dolomite as Soil Conditioner to pH and Exchangeable Al in Inceptisol

Soil fertility is the state of the soil where water, water and nutrients are in a state that is quite balanced and can be obtained according to the needs of plants, including the physical, chemical and biological needs of the soil. Lack of soil fertility will affect plant growth and productivity so that it is less than optimal. Therefore, it is very necessary to increase soil fertility through soil improvement, one of which is dolomite. Inceptisols are soil orders that have not developed further with the characteristics of a thick solum between 1.5-10 meters above the parent material, reacts acidly with a pH of 4.5-6.5, if it undergoes further development the pH increases to less than 5.0, and base saturation is from low to low. currently. The texture of this whole solum is generally clayey, while the structure is crumbly and the consistency is loose. In general, the fertility and chemical properties of Inceptisols are relatively low, but efforts can still be made to improve with appropriate handling and technology, pH in Inceptisol soils is one of the obstacles in efforts to increase soil productivity. The application of dolomite on acidic agricultural soils is to reduce or eliminate the adverse effects of acid soils, which generally contain high enough quantities of exchangeable aluminum ions so that they can poison plants. This test was carried out at the Experimental Field of the Chemical Laboratory of Soil Fertility and Plant Nutrition, Department of Soil Science and Land Resources, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, Sumedang Regency, West Java, which is located at an altitude of 794 m above sea level. The experiment used a randomized block design (RAK). In accordance with the objectives of the experiment, five dolomite test treatments were set with five replications. Dolomite affects the process of increasing pH and decreasing exchangeable Al. Giving the test dose of dolomite equivalent to 1.5 doses of dolomite was able to increase pH and decrease Al-exchable.

Micromorphology of pores and water erosion in Inceptisol soil after application of pig slurry

The application of pig slurry (PS) to soil is known to change its chemical and physical properties. However, little is known about the alterations that PS causes in pore morphology and water erosion. This research evaluated the influence of PS on the morphology of the pores in the surface layer of the soil and on water erosion in an Inceptisol subjected to simulated rainfall. The soil was cultivated with black oats and the treatments (doses) 0, 50, 100 and 200 m3 ha-1 of PS were applied to the crop residue. The experimental design was completely randomized. Six simulated rainfall lasting 60 minutes and planned constant intensity of 65 mm h-1 were applied to the treatments. Undisturbed soil samples were collected in the 0-0.05 m layer, 24 h before and 24 h after the first, third and sixth rainfall events. Image analysis was performed, determining the percentage of macropores and mesopores, number, diameter and shape of the pores, using the micro morphometry technique. PS doses of 100 and 200 m3 ha-1, combined with simulated rainfall, favored surface sealing and pore rearrangement. There was an increase in the number of small and rounded pores, without interconnection between them, with a consequent increase in water erosion until the moment of stabilization of the superficial crust.
