Recognized for his expertise in
land reclamation and
monoculture, Lovink was made an inspector of forests with the
Staatsbosbeheer when it was established in 1899. He continued his studies, briefly attending the
University of Tübingen in the hopes of earning his doctorate. There, he made the acquaintance of Minister
Johannes Christiaan de Marez Oyens, who in 1901 appointed Lovink the Director General of Agriculture, replacing Cornelis Jacob Sickesz. At the same time, responsibility for the directorate – previously under the
Ministry of the Interior – was taken by Marez Oyens'
Ministry of Public Works, Trade, and Industry. In this capacity, Lovink reorganized the
Agricultural and Forestry College in Wageningen in 1904. Renamed the State Higher School for Agriculture, Horticulture, and Forestry, the school began offering the courses necessary for graduates to obtain their teaching certificates. Lovink also developed plans to expand
agricultural education, established the in
Rotterdam, made mandatory the inspection of exported meat, stabilized the , and co-founded the . For his emphasis on
applied agriculture, Lovink was opposed by many university-trained biologists. Lovink remained in this position until 1909, when he was appointed by
Governor-General Alexander Idenburg to replace
Melchior Treub as the Director of the Department of Agriculture, Industry, and Trade of the
Dutch East Indies. Critical of earlier efforts that forefronted native rice agriculture, Lovink instead sought to promote
agricultural expansion by applying
agronomy to improve production techniques. He also initiated forestry programmes and established the Institute for Plant Diseases and Cultures. Lovink entrusted elements without economic import, including the
Lands Plantentuin in
Buitenzorg (now the Bogor Botanical Gardens in Bogor), to
Jacob Christiaan Koningsberger; the latter served as acting director when Lovink took sick leave between 1915 and 1916. Citing health concerns, Lovink left the Indies in 1918, with his position as director taken by J. Sibinga Mulder. On his return to the Netherlands, he was made the Commissioner for Agricultural Production, effective 3 October. ==Political career and death==
