Abstract

Using organic fertilizer as a soil conditioner can increase the C-organic content in the soil. Nutrient content of organic fertilizers include (1) Contains nutrients in types and quantities varying depending on the origin, (2) providing nutrients in a slow (slow release) and in limited quantities, and (3) has the main function to improve fertility and soil health. Organic fertilizers derived from manure are the best soil ameliorants compared to other aminators. Nutrients contained in organic fertilizers are generally low and very varied. As soil amendment material, organic fertilizer helps in preventing erosion and reducing soil cracks. Organic matter as soil enhancers can improve soil physical, chemical and biological properties.

Abstract

Increasing agricultural production can be done by planting a plot of land with various types of plants in a row or alternating cropping patterns. Agricultural cropping systems on dry land in the tropics have specific characteristics and depend on rainfall which can pose a threat to plant survival and the danger of erosion. . In suboptimal land with dry and wet climates, farmers generally plant upland rice alternately with corn and then plant beans. In reality, farmers do not only intercept/rotate between rice and secondary crops but also between crops and crops and/or crops and horticulture (vegetables). This paper aims to present research results related to efforts to increase land productivity by planting a plot of land with several types of plants to increase crop yields and farmers' income. The introduction of a conservation farming cropping system using ground cover and strip plants that produce organic matter is one of the alternatives to the conservation farming cropping system as well as for adaptation to climate change.

Abstract

Acid dry land in the experimental garden Taman Bogo, East Lampung including the classification of Ultisol acil, and generally ultisol acid soils can be used as representative for acid soils in Indonesia.  Characteristic of ultisol soil, among others: sour soil reaction (low pH <5.5), high aluminium content, high P fixation, exchangeable base contents and low exchange capacity (CEC), iron and manganese content close to poisonning, sensitive erosion and poor biotic elements. Acid dry land in Indonesia is directed in supporting the improvement of land resources, Display/ Show window and visitor plot development of acid dry land management technology, implemented to accelerate the process of superior technology transfer such as fertilizer technology and the use of organic materials, conservation, reclamation and land rehabilitation, as well as superior varieties in acid dry land.  Show window dan visitor plot  development of dry land management technology in Taman Bogo experimental garden is a means of discussion and communication between researchers, extension workers, farmers and local policy makers.
