Penelitian ini bertujuan mengkaji pengaruh pupuk hayati mikoriza, pupuk organik limbah media jamur dan pengurangan dosis anjuran pupuk kimia sintetik Urea, SP-36 dan KCl terhadap nilai Berat Jenis Partikel (BJP), Berat Jenis Isi (BJI), Batas Cair (BC), Batas Lekat (BL), Batas Gulung (BG), Batas Berubah Warna (BBW), porositas dan hasil tanam buncis. Penelitian dilaksanakan dilahan petani di Desa Suro, Kecamatan Kalibagor, Kabupaten Banyumas dan di Laboratorium Ilmu Tanah Universitas Jenderal Soedirman. Penelitian menggunakan Rancangan Acak Kelompok (RAK). Faktor pertama yang dicoba adalah pemberian pupuk hayati mikoriza campuran Glomus dan Gigaspora sp (H). Faktor kedua adalah pemberian pupuk kimia sintetik NPK pengurangan 50% dosis anjuran (C). Faktor ketiga adalah pemberian pupuk organik limbah media jamur (K). Perlakuan dirancang dalam bentuk faktorial lengkap 23 sehingga diperoleh 8 kombinasi perlakuan, dan masing-masing diulang sebanyak tiga kali sehingga diperoleh 24 unit percobaan. Hasil penelitian menunjukkan bahwa aplikasi pupuk hayati mikoriza Glomus dan Gigaspora memberikan pengaruh nyata terhadap sifat fisika tanah yaitu batas gulung, berat jenis isi, berat jenis partikel, porositas dan hasil tanaman buncis.

The aims of the research is to study the effect of mycorrhizal biofertilizer, organic fertilizer waste fungus and the reduction recommended dosage of synthetic chemical fertilizers Urea, SP-36 and KCl on  some soil physical properties namely the Particle Density, Bulky Density, Liquid Limit, Sticky Limit, Border Roll, Colour Change Limit, porosity and the production of bean. The experiment was conducted in the village of farmers in a land of Suro, Kalibagor, Banyumas and at the Laboratory of Soil Science University of Jenderal Soedirman. The research using Randomized Block Design (RBD). The first factor is application of  mixed biological fertilizer mycorrhizal Glomus and Gigaspora (H). The second factor is the reduction 50% of recommended dosage of sintetic fertilizer NPK (C). The third factor is the  organic fertilizer waste fungus (K). The treatment is designed 23 in the form of a full factorial with eight treatment combination and each repeated three times to obtain 24 experimental unit. The results showed that the application of mycorrhizal biofertilizers Glomus and Gigaspora significant affect on the soil physical properties i.e. limit roll, bulky density, particle density, soil porosity  and the production of bean.
