Abstract

The main dry land is land that is formed in areas with high rain intensity (> 2000 mm / year). The main dry land has a pH of (powder) (cattle), the saturation of the base (KB), n, p and k low content and high al saturation. Target this researcher is to study the influence of the addition of biochar enriched by Trichoderma sp. With the nutrition of the cane drops (molasses) against some of the nature of the soil and growth of the tall. This research was conducted using complete randomized design (RAL), with treatment among others: P0: without treatment; P1: biochar 30 gram; P2; Thrichoderma sp. + molase 80 ml; P3: biochar 30 gram + Trichoderma sp. + molasses. Every treatment is repeated 5 times. Plant indicators on this research are tall colors. The plant observation parameters include high plants, leaves, wet biomass and dry biomass plants. The results showed that the addition of bioochars were enriched with Trichoderma sp. Not having a real effect on the growth of tall colors that covers the plant, the number of leaves, dry biomass, and plant wet biomass. Biochar treatment enriched with Trichoderma sp. Not different real with biochar without enriched Trichoderma sp. However, these two treatments can increase c-organic and P-available land. It is advisable to do more research on diosis of biochar and trichoderma sp. In order to improve the chemical properties of the land and try to use other indicators that are more responsive to the factors of the har in the soil, such as corn.. Keywords: the main dry land, biochar, Trchoderma sp., molsses, kale plant

Abstract

This study aimed to determine the effects of applying 50 t ha?¹ of compost, made from a mixture of cow dung, bromelain waste, and chopped bamboo, on soil compaction and penetration in pineapple (Ananas comosus L. Merr.) plantations in Central Lampung, Indonesia. This study used a survey method at four locations, each representing a different age of pineapple plants. Soil penetration analysis was performed using a Digital Cone Penetrometer. Soil bulk density and total pore space were determined using the volumetric method. The results indicated that soil compaction decreased with increasing pineapple plant age, corresponding to a reduction in soil bulk density. Specifically, the soil bulk density values for pineapple plants at 0, 3, 5, and 9 months after planting (MAP) were 1.42 g cm?³, 1.23 g cm?³, 1.13 7 g cm?³, and 1.02 g cm?³, respectively. Lower soil bulk density corresponded to less soil compaction, leading to lower soil penetration resistance. The lowest soil penetration value was recorded at location 9 MAP, while other locations remained below the critical soil penetration limit. A lower soil penetration value indicates reduced soil strength. There was a positive correlation between soil bulk density and specific gravity, and between soil penetration and age at 5 and 9 months. Conversely, higher soil pore space and dispersion index were associated with decreased soil penetration. In conclusion, applying 50 t ha?¹ of compost appears to be an effective solution for pineapple cultivation.
