In 1898, Soskin accompanied Theodor Herzl during his visit to Palestine, and subsequently assisted in research to examine the possibilities for agriculture in different regions in the country. In 1903, he participated in the Sixth Zionist Congress, where he was elected to the Committee for the Study of Eretz Israel, along with Otto Warburg and Franz Oppenheimer. In connection with the works of the committee, he was part of a delegation to El Arish, in the northern Sinai, to investigate the area at the request of Herzl. Part of his agricultural research was conducted in collaboration with Aaron Aaronsohn, with whom he became friends while in Zichron Yaacov in the early part of the twentieth century.[citation needed]
In 1918, he was appointed Director of Settlement on the Jewish National Fund (the "JNF") and, following a tour of Europe, began to examine the implementation of an agricultural model. The model included intensive agriculture on small plots of land. He tried to implement this model in the Binyamina district, and it saw success with the founding of Nahariya in 1934. He also championed the use of hydroponics - the growth of plants on water; in 1944, he proposed a plan to feed liberated Europe with hydroponic vegetables.[1]
