“…The water content change for most plots observed were sensitively depended on rainfall and irrigation rate, which was due to the basic characteristics of loamy-sandy soil having high total macro-pore inside [45,46,54,55]. Specifically, the higher capability of CM over others in intercepting and distributing rainfall and irrigation water within soil profile as well as preventing upward water loss by evaporation verified its prospective applicability in crop cultivation to support better water management [7,34,47,52].…”

“…During last couple of decades, mulch has been utilized in agriculture due to its benefit in maintaining soil moisture and temperature, reducing erosion impact, suppressing weeds and insects, and enhancing soil nutrients [1,5,7,9,11,17,25,45,50]. Over various types of mulches, plastic is the most common mulch, which is low cost and easy to be applied [56].…”

Soil-water dynamics pattern in a lettuce cropping field under cotton mulch (CM), plastic mulch (PM), and zero mulch (C) coverage was characterized. Three lettuce plots of 300 cm x 100 cm large each were prepared. Soil-water content, electrical conductivity (EC) and temperature at 0-10 and 10-20 cm depth were monitored hourly. Soil-hydraulic conductivity (K us ) within each soil profile was characterized and modelled using van-Genuchten model. The soil with CM showed higher water content (0.29-0.33 cm 3 cm −3 ) than that with PM (0.29-0.31 cm 3 cm −3 ) and C (0.26 cm 3 cm −3 ). At 32.1 mm d −1 rainfall rate, the soil EC with CM (0.22-0.30 dS m −1 ) was higher than others (< 0.02 dS m −1 ). The soil temperature with CM was 2-3 and 4-5 °C lower than that with PM and C, respectively. Furthermore, the CM plot had higher K us (3.1-4.4 cm d −1 ) compared to the PM (0.18-0.21 cm d −1 ) and C plot (0.36 cm d −1 ). The results reflect a unique characteristic of the cotton mulch, which is able to provide sufficient water and nutrient availability, and to control weeds and temperature in soil profile, for effective growth as well as sustainable production of the crop.

“…Erosi yang terjadi pada perlakuan G1 sebesar 35,30 ton ha -1 sedangkan pada perlakuan G2 sebesar 9,54 ton ha -1 atau berkurang 72,97%. Hasil tersebut sejalan dengan penelitian Wijaya (2020) yang menunjukkan bahwa penggunaan guludan horizontal (memotong lereng) dengan aplikasi bio-arang serta perlakuan mulsa plastik-pupuk anorganik mampu menahan laju aliran permukaan dan erosi pada tanaman kentang dengan masing-masing sekitar 11,9 -18,1% dan 41,8 -48,1%. Penggunaan pupuk organonitrofos 40 ton ha -1 (P1) sangat nyata mengurangi terjadinya erosi dibandingkan tanpa penggunaan pupuk organonitrofos (P0).…”

Ubi kayu dianggap sebagai tanaman yang menguruskan tanah, karena banyak mengambil unsur hara dan dianggap kurang mampu melindungi tanah dari pukulan air hujan sehingga menjadikan lahan ubi kayu peka terhadap erosi. Tindakan konservasi tanah berupa pembuatan guludan dan pemberian pupuk organonitrofos merupakan upaya untuk mengurangi laju aliran permukaan dan erosi khususnya pada lahan pertanaman singkong varietas Gajah (Manihot esculenta Crantz). Penelitian ini bertujuan untuk mengetahui pengaruh guludan dan pupuk organonitrofos terhadap aliran permukaan dan erosi pada pertanaman singkong. Penelitian dilaksanakan di Laboratorium Lapang Terpadu dan Laboratorium Ilmu Tanah Fakultas Pertanian Universitas Lampung pada bulan Januari hingga Oktober 2020. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap (RAKL) faktorial 2 x 2, dengan 4 ulangan sehingga diperoleh 16 satuan percobaan. Faktor pertama adalah tindakan konservasi yang terdiri dari G1 (guludan searah lereng) dan G2 (guludan memotong lereng), dan faktor kedua meliputi pemberian pupuk organik organonitrofos yang terdiri dari P0 (tanpa pupuk organonitrofos) dan P1 (pupuk organonitrofos dengan dosis 40 ton ha-1. Hasil penelitian menunjukkan bahwa penggunaan guludan memotong lereng lebih baik dalam mengurangi aliran permukaan dan erosi dibandingkan guludan searah lereng pada pertanaman singkong Gajah. Aliran permukaan 279,44 mm menjadi 213,68 mm (23,53%) dan erosi 35,30 ton ha-1 menjadi 9,54 ton ha-1 (72,97%). Selain itu, Pemberian pupuk organonitrofos 40 ton ha-1 memberikan hasil yang lebih baik dalam mengurangi aliran permukaan dan erosi dibandingkan tanpa pupuk organonitrofos. Aliran permukaan 286,42 mm menjadi 206,69 mm (27,83%) dan erosi 27,19 ton ha-1 menjadi 17,65 ton ha-1(35,08%).

“…Tindakan konservasi tanah yang dapat dilakukan adalah penggunaan mulsa, penutupan lahan dengan mulsa khususnya mulsa jerami dengan komposisi 4 ton ha -1 memberikan pengurangan erosi yang relatif besar (Parhadi, 2015). Selanjutnya Wijaya et al (2020) melaporkan bahwa kombinasi mulsa jerami dan pupuk organik dapat menekan laju aliran permukaan dan menekan kehilangan unsur hara nitrogen dan fosfor.…”

This research was conducted in Kampili Watershed, South Sulawesi. This research was conducted from February to April 2021. This study was conducted using USLE method and USLE formula as an analysis tool to determine the rate of erosion and tolerable erosion as well as identification of damaged land in the Kampili watershed of south Sulawesi. The results showed the rate of erosion that occurs in each land use, namely, in plantation land use has an erosion rate of 94.54-ton ha -1 per year, in the use of mixed plantation land medium density has an erosion rate of 281.10-ton ha -1 per year, in the use of rice fields has an erosion rate of 4.13-ton ha -1 per year and in the use of open land has an erosion rate of 853.53-ton ha -1 per year. The value of erosion that can be tolerated (T) of each land use is, in the use of farmland has a value of T of 17.66-ton ha -1 per year, in the use of mixed garden land density has a value of T of 15.99-ton ha -1 per year, in the use of rice fields has a value of T of 16.40, in the use of open land land has a value of T of 12.25-ton ha -1 per year. Meanwhile, for the identification of damaged lands is determined by looking at the value of erosion class that is light, very light, medium, heavy and very heavy.
