“…Upaya konservasi tanah yang dilakukan di kampung Cibeureum bersamaan dengan konservasi air. Hal ini disebabkan konservasi tanah merupakan kesatuan tidak terpisahkan dengan konservasi air (Hu et al, 2022). Konservasi tanah dan air yang dilakukan bersamaan dapat meningkatkan hasil pertanian dan mengurangi air run off dan kehilangan tanah, serta memperbaiki ekosistem (Adimassu et al, 2017).…”

Ketahanan pangan untuk mencapai masyarakat yang sehat ditentukan oleh usaha di bidang pertanian. Petani di kampung Cibeureum desa Sukanagalih, kecamatan Pacet Kabupaten Cianjur Jawa Barat merupakan pemasok produk hortikultura untuk di wilayah sekitarnya dan DKI Jakarta. Permasalahan yang dihadapi petani adalah seringnya mengalami kerugian akibat ongkos produksi pertanian yang tinggi seperti untuk pembelian pupuk dan pestisida. Masalah lain adalah sistem pemasaran yang masih konvensional dan kurang memperhatikan permintaan pasar. Jika masalah ini terus berlanjut dikhawatirkan akan menimbulkan dampak terhadap ekologi, ketahanan pangan, ekonomi dan sosial yang lebih serius. Alternatif penyelesain masalah adalah menerapkan model pertanian berkelanjutan melalui konservasi tanah dan air serta meningkatkan kemampuan e marketing. Tujuan PKM adalah meningkatkan pengetahuan dan kemampuan petani untuk menerapkan konservasi tanah dan air serta pemasaran hasil pertanian melalui WA group. Metode yang digunakan adalah mengadakan workshop mengenai upaya konservasi air dan tanah, pemberdayaan petani untuk membuat 1 embung dan 3 kolam, serta workshop pemanfaatan WA group untuk promosi hasil pertanian. Capaian hasil dari kegiatan ini adalah terwujudnya 1 embung dan 3 kolam sehingga terpenuhinya kebutuhan air untuk 7 hektar lahan pertanian, 5 orang petani menerapkan konservasi tanah secara mandiri serta peningkatan produksi tomat sebesar 100% dan jumlah masa panen dari 8 kali menjadi 16 kali. Pemanfaatan WA group untuk e marketing juga dapat dilakukan oleh 6 orang petani mitra. Walaupun baru 2 orang yang aktif membuat konten promosi, namun sudah ada pengusaha kuliner mengirimkan kualifikasi jenis sayur yang diperlukan.

“…The Mollisol region of Northeast China (often called black soils) is one of the four Mollisol regions globally and plays a pivotal role in national grain production in China (Liu et al, 2012). However, this region is experiencing severe soil degradation due to soil erosion, excessive reclamation, and adverse management practices (Hu et al, 2022; Wang et al, 2021). The prevalence of soil degradation in the region breaks the soil water and air balance, decreases soil fertility, decreases soil quality, and thereby compromises the agricultural production capacity (Liu et al, 2010; Wen et al, 2021; Yang et al, 2022).…”

“…The prevalence of soil degradation in the region breaks the soil water and air balance, decreases soil fertility, decreases soil quality, and thereby compromises the agricultural production capacity (Liu et al, 2010; Wen et al, 2021; Yang et al, 2022). In addition, the Mollisol region contains a rich soil organic carbon (SOC) stock (Hu et al, 2022), and serious soil degradation accelerates the depletion of SOC in this region, which is admittedly related to global warming (Garbowski et al, 2023; Li & Han, 2016). Therefore, necessary and urgent measures are needed to combat soil degradation, particularly when extreme climate events are perceptible.…”

Soil degradation in the Mollisol region of Northeast China is ubiquitous partly due to poor soil hydraulic characteristics. Improving soil hydraulic characteristics thus delivers benefits to soil sustainability. In this study, the effects of organic amendments on soil hydraulic characteristics were explored at the laboratory scale. Soil samples were subjected to three low‐cost and eco‐friendly organic amendments, including corn straw juice (CSJ), fulvic acid (FA), and humic acid (HA). The soil infiltration capacity, soil water characteristic curve (SWCC) and soil water retention capacity were determined by using a steel‐ring method and a centrifuge method. The parameters of the SWCC were fitted by a van Genuchten (VG) model, and the specific water capacity [C(h)] was calculated. In addition, bulk density (BD), macroporosity, and soil organic matter (SOM) were measured, and the relationships between the variables and processes were evaluated. The results indicated that the soil infiltration capacity (i.e., initial infiltration rate, cumulative infiltration, and steady infiltration rate) was significantly increased in the CSJ and FA treatments (p < 0.05) but decreased in the HA treatment compared to the control (CK) treatment. All the selected organic amendments improved the soil water release and supply capacity, and the CSJ2 treatment showed the best effect. The incorporation of CSJ, FA, and HA significantly improved the soil water retention capacity by increasing the saturated soil water content, field capacity, and plant available water capacity (p < 0.05). Such changes were significantly associated with macroporosity and SOM (p < 0.05). In this sense, our results showed that the CSJ treatment with 4 L m−2 and 50% volumetric concentration could be an effective soil amendment to improve the soil hydraulic characteristics in Mollisols and deserves further research.
