Lembah Hijau 1 Farmer Group in Mempawah Regency grows leafy vegetables and watermelon on peatland, with land preparation that still follows habit and without field observation of soil conditions. This community service activity aimed to equip farmers to observe field conditions and to determine land preparation suited to soil conditions and horticultural crops. The method was non-formal education through extension, consisting of a lecture, discussion of farmers' experience, an on-site soil measurement demonstration with a digital rapid soil tester, an introduction to visual diagnosis of nutrient deficiency symptoms on maize, and a discussion of land preparation options, supported by a leaflet and a field worksheet. The activity was held on 7 May 2026 and attended by 10 of the group's 20 members. The results were the delivery of material on field parameters to observe before planting, namely acidity, moisture, temperature, and nutrients, illustrated by pH readings of 4.6 and 4.4 on two plots differing in watering and shading, and the introduction of N and K deficiency patterns on maize. Farmers were given stepwise land preparation recommendations: dolomite at 500 kg/ha and cattle manure equivalent to 2 t/ha (previously no dolomite and 1 t/ha manure), water and bed management by crop, and fertilization following the district recommendation book. The activity can serve as an extension model for peatland preparation, followed by mentoring and monitoring of crop response
