Abstract

Erosion is one of the problems in agricultural activities. Soil erosion can cause loss of topsoil that contains nutrients for plants. The diversity of land use in agricultural activities affects the amount of erosion that occurs. This research aims to identify the level of erosion hazard in several agriculture land use and the determine factor of erosion, as well as provide direction for conservation in Sidoharjo District, Wonogiri, Central Java. This research is a survey research with exploratory descriptive approach based on the results of field observation and laboratory analysis. Sampling points were determined purposively on 12 land units. Parameters observed were soil texture, soil structure, organic matter, permeability, slope length and slope, vegetation, and conservation management. The results showed that the level of erosion hazard in the study area contained light, moderate, and severe erosion hazard levels, and moorland have the highest level and paddy field have the lowest level of erosion hazard. The determinant factors of soil erosion are plant management / vegetation and slope length/slope gradient. Conservation directions that can be carried out in Sidoharjo District for land use management improvement are a combination of vegetative conservation techniques such as the use of organic mulch and plant management to increase organic matter and mechanical conservation techniques such as terrace repairs to minimize soil loss.

Abstract

Paddy is the main crop in the tidal land farming system. The use of tidal land, especially for rice plants, faces many obstacles, in general it has low fertility due to the lack of macronutrients N, P, K as well as high and varied agrophysical constraints. For this reason, in rice cultivation, Alluvial land needs ameliorant that is easy to obtain and cheap in price, to help increase Alluvial soil fertility in addition to N, P and K fertilizers. The research was carried out by taking soil samples in Sei Kakap in 2 different locations, and then the samples were analyzed at the Chemistry and Soil Fertility Lab of Faperta Untan. This study used a dose of empty fruit bunches (tankos) biochar and chicken manure with a ratio of 25% : 75%, 50% : 50% and 75% : 25%. The treatment was repeated 5 times, so there were 15 treatments. The design used is the completely randomized design. The results of the study explain that from the incubation experiment between biochar tankos, chicken manure, for 4 weeks the C/N ratio was <20%, besides that base saturation and CEC were higher than 2 weeks incubation, indicating that the use of organic biochar tankos + chicken manure with a ratio of 25:50 and 50:50 can increase the fertility of paddy fields.

Abstract

Upland rice productivity in Kampar has decreased due to inappropriate planting time with rainfall. Plant water needs will not be met during the dry season and are at risk of crop failure. This study aims to determine the level of availability of groundwater based on land water balance analysis and determine the planting time of upland rice. The method used in this research was a survey method. Soil data of bulk density, field capacity water content, permanent wilting point moisture content, soil texture, and C-organic content were obtained with ring and composite soil samples. Soil sampling points were determined based on the results of overlaying the soil map and land use map using GIS techniques. Climate data for the period 1990–2019 was obtained from the Sumatra River Region III Center. Analysis of land water balance was carried out using the Thornthwaite-Matter method. The results showed that Kampar Regency was classified as a wet area with an annual rainfall of 2,508 mm (Oldemann D1). Soil water content was classified as a sufficient criterion every month, except for June–August. The planting of upland rice at SLH 1–SLH 7 (inpago variety) can be done in January, May, and September, while at SLH 8, it is done in January and September. Planting using local varieties at SLH 1–SLH 7 can be done in February and September, while at SLH 8, it is done in March and September. Alternatif planting can also be done by planting inpago varieties in February and local varieties in September.

Abstract

Oil Palm Plants (Elaeis guineensis Jacq.) are one type of plantation crop that occupies an important position in the agricultural sector in general, and the plantation sector in particular. Oil palm can grow in Ultisol soil which has a low fertility level. The characteristics of the elements in the soil greatly influence the characteristics of the elements in the plants that grow on it, so that the content of essential and non-essential elements that are deficient or excessive in plant tissue will reflect the content of the elements in the soil. The aim of this research is to analyze the nutrients magnesium, calcium and sodium as well as the soil base saturation of ultisol on oil palm land in Kelompu Village, Kembayan District, Sanggau Regency. The method used in this research is the survey method and soil sampling using the grid system method. The observation point represents a land area of 1,000 x 1,000 m or 10 ha. Soil samples or specimens are taken at a depth of 0-30 cm in a composite manner for the purpose of analyzing the chemical properties of the soil. Oil palm fields in Ultisol soil for all locations have almost the same soil chemical properties of magnesium, calcium and sodium, that is, they tend to have chemical properties that are classified as low class.
