Physical properties of soil are good for plant growth is closely related to the management of the soil, so it will need to integrate of physical properties to get an overall assessment with making soil physical quality index (SPQI). This study aims to an evaluation of physical properties and determines the physical quality index using several unit treatments to produce various physical qualities on Groundnut/Arachis hypogeal L. The location of the research was carried out in a farmer's garden in Cimaung Village, Cikeusal District, Serang Regency, Banten Province (Coordinates 6o12’14’’ S dan 106o11’52’’E). To analyze the SPQI using several physical properties of the soil such as texture, bulk density, porosity, permeability, and aggregate stability. Each indicator has a scoring parameter to assess the soil physical quality index with a score range of 0-5. An assessment SPQI in a land unit is able to describe the various physical qualities of the soil which are represented by several physical properties of the soil. The unit treatment which class categorization of soil physical quality index indicated slightly good (U2), medium (U1, U3-U6), and slightly poor (U7) as a control.
Increasing suboptimal soil productivity in agricultural land to increase food production needs to be encouraged. A proper land management design is necessary to overcome the various obstacles and problems faced to increase suboptimal soil productivity. The purpose of this research, which was conducted at ex rice field of suboptimal soil, was to improve suboptimal soil productivity for plantation peasants by developing soil management recommendations, mainly through a combination of inputs needed to optimize the growth and productivity of potato plants based on soil conditions. A combination of lime dosage and organic matter (Petroganic) dosage with basic fertilizer (urea, N-P-K, and dolomite) were applied by using a Randomized Completely Design (RCD) for 8 (eight) treatments with three replication. The results showed that P4, treatment with the highest lime dosage, and Petroganic produced the highest fresh groundnut pod. It can increase production as high as 89% as compared to control. All treatment combinations of lime and Petroganic increased fresh nut pod between 46% to 89% compared to control. The use of basic fertilizer only increases production by 32% as compared to control. To achieve higher fresh nut pod yield, watering or irrigation should be included in soil management.
Increasing potato productivity on suboptimal soil is needed since people in various food types widely consume potato. The research was conducted at the BB-Biogen Segunung-Pacet, Cipanas District, Cianjur Regency, West-Java Province that is characterized by soil with acidic reactions, medium organic matter content and low total organic-N and exchangeable-Mg, very high available-P, high exchangeable-Ca, and K. The increasing of productivity, is designed through providing various levels of lime, manure fertilizer, and Bioboost along with basic fertilizers (ZA, SP36, and KCl). Overall, there were ten treatments, namely, 1) P1 (lime level 1, manure fertilizer level 1, basic fertilizer); 2) P2 (lime level 1, Bioboost level 1, basic fertilizer); 3) P3 (lime level 2, manure fertilizer level 1, basic fertilizer); 4) P4 (lime level 2, Bioboost level 1, basic fertilizer), 5) P5 (lime level 1, manure fertilizer level 2, basic fertilizer); 6) P 6 (lime level 1, Bioboost level2, basic fertilizer); 7) P7 (lime level 2, manure fertilizer level 2, basic fertilizer); P8 (lime level 2, Bioboost level 2, basic fertilizers); and 9) P9 (basic fertilizers), 10) P10 (control, without lime, Bioboost, manure fertilizer and organic fertilizer). P5 treatment resulted in the best growth and production of potato. The combination of the largest manure fertilizers and low-level lime provided the highest increase in productivity.
Many smallholder cocoa farmers in Polman, West Sulawesi-Indonesia breed goats traditionally on hilltop of the sloped cocoa farms. The goat’s manure is deposited under the pens, not distributed on the farm. We investigated the significance of this traditional goat breeding on the hilltop of sloping cocoa farms on soil quality based on the distance from the pens along the slope direction. We selected three sloped-cocoa farms where this traditional model had been practiced for years. The farms studied had 30 to 70% slopes, clay loam to clay soil textures. Along a transect lane, 0-5, 5-10, and 10-15 meters from the pen on each farm, we measured soil bulk density, hydraulic conductivity (HC), soil organic carbon (SOC), pH, soil nitrogen, phosphorus, potassium, cation exchangeable capacity (CEC) and earthworm population. This traditional practice improved soil quality compared to the adjacent farms which were not affected by the practice (control). Soil HC, SOC, N, P, K and CEC, and earthworm population were markedly higher under this system compared to the control, especially at 0 to 5 m distance from the manure deposit. The beneficial effects of this system were limited only within 10 m from the pens, beyond which soil quality was practically similar to the control site. This traditional system may be considered as an appropriate practice for soil quality maintenance in sloping cocoa farm, but an improvement is needed for greater benefits and reduced risks through terrace construction and manure deposition every 5-10 m range along the slope.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
