Abstract

The use of Trichoderma is one effort to manage healthy and environmentally friendly plants. This fertilizer is part of organic fertilizer; which farmers do not widely practice yet. This fertilizer has an impact that can increase nutrients and soil fertility. This study examined the impact of using Trichoderma in combination with NPK fertilizer on soil nutrient, nutrient uptake, and growth of corn plants. A Completely Randomized Block Design consisting nine treatments with three replicates was applied. The treatments were Control (A), standard NPK (Urea 350 kg ha-1, SP-36 200kg ha-1 and KCl 75kg ha-1) (B), ¼ NPK + 5 kg ha-1 Trichoderma (C), ½ NPK + 5 kg ha-1 Trichoderma (D), ¾ NPK + 5 kg ha-1 Trichoderma (E), 1 NPK + 5 kg ha-1 Trichoderma (F), ¾ NPK +1.25 kg ha-1 Trichoderma (G), ¾ NPK +2.5 kg ha-1 Trichoderma (H), ¾ NPK + 3.75 kg ha-1 Trichoderma (I). The results showed that NPK fertilizer accompanied by Trichoderma increased soil total N by 84.21%, available P by 36.25%, and available K by 142.22%. The same treatment also increased corn plants’ N, P, and K nutrients by 52.71%, 106%, and 61.53%. The growth of maize plants from applyingTrichoderma up to 5 kg ha-1 has not reduced the use of NPK fertilizer yet. However, applying Trichoderma could improve soil fertility.

Abstract

Excessive pesticide use and intensive shallot farming to satisfy high market demand can degrade soil quality and harm environmental sustainability. Sustainable agricultural practices, such as biochar and compost are alternatives to ensure long-term soil productivity and fertility. This study aimed to investigate the ability of biochar and compost made from bagasse waste to improve shallot growth, yield, nutrient absorption, and soil quality. The research used a factorial randomized block design in a greenhouse. The first factor was the application of biochar and compost (K1 = compost, K2 = biochar, K3 = biochar-compost (1:4/w:w) and K4 = biochar-compost (1:2/w:w), and the second factor was the dose of NPK fertilizer (0%, 50%, and 100% of the recommended dose). The planting medium used was an Inceptisol from shallot fields in Sukaharjo, Central Java. The variables measured included plant growth, yield components, soil chemical properties, and levels of N, P, and K in plants. The results showed that the combination of compost with 100% NPK fertilizer gave better results in plant growth, fresh and dry weight of plants and tubers, increased organic C, total N, and CEC of the soil, and increased the absorption of N, P, and K by plants.

Abstract

Plant canopies can protect the soil surface from raindrops and rooting activities that cause changes in biophysical properties. A low infiltration rate will reduce the soil’s capacity to store water to be low, resulting in a high soil erodibility value. This research aims to obtain infiltration values on different land cover, analyze the effect of land cover on soil infiltration rate, and analyze the effect of soil infiltration rate on soil erodibility. The research includes exploratory, descriptive research with a purposive sampling method. The study results show an increased soil infiltration rate can reduce soil erodibility. The infiltration rate of 74-year-old mahogany land cover ranged from 1.94–3.03 cm/hour, 50-year-old mahogany 1.61 cm/hour, old pine 1.53–1.89 cm/hour, old tapped pine 1.54–3.43 cm/hour, young pine 0.48–1.60 cm/hour, young pine 0.37–0.61 cm/hour, and 5-year-old sonokelling 0.56–0.73 cm/hour. The highest infiltration value is in 74-year-old mahogany and the lowest in young pine. The highest soil erodibility value is in young tapped pine and the lowest in 50-year-old mahogany. Erodibility is the sensitivity of soil to erosion. It is easier to erode if its erodibility value is higher; conversely, erosion is less likely to occur if its erodibility value is lower. An increase in soil infiltration rate can reduce soil erodibility. Keywords: Horton method, land cover, Mount Bromo, soil erodibility, soil infiltration rate

Abstract

High rainfall caused the overflow of the Wiroko river, causing flooding in Nguntoronadi. This study aims to analyze flood potential, provide evaluation and recommendations on areas that have high flood suscetibility. Type of research is quantitative descriptive by using the overlay method of scoring land characteristics that affect environmental conditions.  Land characteristics are rainfall, altitude, slope, soil type and land use. The characteristics of the land  are overlayed using the ArcGIS application to determine a map of flood susceptibility index, and the data were analyzed using descriptive methods. The result found three categories of flood susceptibility indexes: low, medium, and high. The study revealed a total area flood susceptibility of 6566.52 ha, with 33.79% having high flood susceptibility. The potential for high flood vulnerability is found in lowland, high rainfall and open land use. Areas which has a high flood susceptibility by improving river flow, drainage and terraces in rice fields. The high flood susceptibiity caused by rainfall, lowland and low vegetation as well as high human populations.
