Abstract

Permanent raised-beds can be used in several soil seasons and aim to increase production through the application of sustainable and sustainable agriculture and can improve the welfare of farmers. The three basic principles of conservation agriculture are: i) applying minimal or no tillage ii) applying cover crops continuously throughout the year, and iii) applying crop diversification, either by intercropping, crop rotation, and consecutive cropping (relay cropping), especially between non-legume and legume crops. Service activities provide knowledge to farmers by demonstrating the application of permanent bed farming techniques to reduce farm production costs. This activity is expected to: 1) as an example of the application of permanent bed-based agriculture to prevent soil erosion by planting cover crops and mulch, 2) as an example of a permanent bed technique to maintain soil stability and save costs, 3) as an example of a natural way to restore physical, chemical and biological fertility of dry soil, and 4) as an example of how to increase soil productivity in dry paddy fields typology. To achieve this, several conservation methods will be introduced, as well as several types of vegetable crops and minimum tillage techniques will be introduced.

Abstract

Sektor pertemakauan di NTB memang sudah mendunia, bukan hanya dari segi produksi tapi juga kuwalitas yang mumpuni setelah Berazil. Melihat besarnya budidaya tembakau di Lombok yang hampir terdapat di semua Kabupaten dan merupakan salah satu komoditi andalan yang sudah lama dikembangkan, sehingga perlu dilakukan evaluasi lahan yang tepat dalam mendukung pengembangan budidaya tembakau khususnya tembakau “Virginia Lombok”. Hasil evaluasi lahan yang dilakukan di Kabupaten Lombok Timur di 4 Kecamatan yang merupakan sentral budidaya tembakau memperlihatkan bahwa kelas kesesuaian lahan cukup sesuai (S2), dengan melakukan beberapa upaya perbaikan untuk meningkankan potensi lahan. Ada beberapa faktor penghambat yang ditemukan dil apangan curah hujan yang telalu tinggi mencapai 1457 mm/tahunnya, retensi hara (rerata KTK: 44.42 %meq; pH [H20] 6,73; K-tersedia: 3,51 serta kandungan BO: <1,19%). Selain itu tingkat kelerengan andil dalam menghabat budidaya tembakau karena akan mempercepat laju limpasan permukaan. Dengan ada faktor penghambat maka perlu diadakan upaya perbaikan untuk meningkatkan kelas kesesuain lahan seperti: Pembuatan saluran irigasi memadai, Pembuatan embung, penyemprotan zat kapur untuk menekan tingkat kebasaan pada tanah (pH >7,5), dan Penambahan Bahan organik dengan pengembalian sisa tanaman atau mengurangi menggunakan pupuk sintetik

Abstract

This study aims to determine the potential of biochar on the mobility of mercury (Hg) in polluted soil planted with mustard greens (Brasicca juncea) and to determine the growth response of mustard greens (Brasicca juncea) in absorbing mercury (Hg). This study used the experimental method, which is a method that aims to examine the effect of biochar application at various doses on the mobility of mercury using the indicator plant mustard greens (Brasicca juncea L) in mercury (Hg) polluted soil. This experiment was carried out from March to June 2023 in the Greenhouse of the Faculty of Agriculture, University of Mataram. Soil samples were collected in Pelangan Village, Sekotong District, West Lombok Regency at several points near the gold processing unit. The samples were taken at top soil of 30 cm with a distance of 100 cm from the processing site then composited. Soilschemical properties including concentration of Hg before and after experiments were measured. Agronomic variables include fresh and dry weight of roots, total dry weight of and concentration of Hg) in plant tissue were also measured. The results of the study showed that the application of rice biochar reduced mobility of Hg in soils. The concentration of extractable-Hg in biochar-treated soils were lower compared to control. This is likely related to the potential adsorption of a number of IHg and MeHg by the negative surface of the biochar and also the formation of association of Hg bonds with the functional groups of the biochar. However, this needs further confirmation.
