Penelitian ini dilakukan untuk mengetahui pengaruh aplikasi hidrogel terhadap beberapa sifat atau karakteristik tanah: kadar air, stabilitas agregat, porositas makro, dan kandungan C-organik. Penelitian dilakukan pada bulan September sampai dengan November 2013 di rumah kaca dan laboratorium fisika dan kimia tanah Fakultas Pertanian Universitas Padjadjaran dengan ketinggian tempat ± 700 m di atas permukaan laut. Penelitian ini ditata dalam satu rancangan dasar berupa Rancangan Acak Kelompok yang meliputi 4 perlakuan dan 5 ulangan. Perlakuan tadi adalah: dosis hidrogel 0 gr polybag-1 (H0), dosis hidrogel 100 gr polybag-1 (H1), dosis hidrogel 200 gr polybag-1 (H2), dan dosis hidrogel 300 gr polybag-1 (H3). Hasil penelitian menunjukkan bahwa aplikasi hidrogel berpengaruh nyata terhadap hampir semua variabel yang diamati (stabilitas agregat, porositas makro, dan C-organik), akan tetapi aplikasi hidrogel tidak berpengaruh nyata terhadap kadar air tanah.
The experiment was conducted to find out the impact of hydrogel application on some soil characteristics (water content, agregat stability, macro porosity, and C-organic content). The experiment was done from September up to November 2013 in greenhouse area of Agriculture Faculty – Padjadjaran University, with altitude of about 700 m above sea level. Randomized block design was used in this experiment which consisted of 4 treatments and 5 replications. Treatments in this experiment were: hydrogel dosage of 0 gr polybag-1 (H0), of 100 gr polybag-1 (H1), of 200 gr polybag-1 (H2), and of 300 gr polybag-1 (H3). The results showed that, most of response variables (aggregate stability, macro-porosity, and C-organic content) were relatively affected by hydrogel application. Meanwhile, the application of hydrogels did not affect soil water content.
