farming system
organic agriculture
No N mineral fertilizers were used but 42 kg K ha-1 of and 20 kg P ha-1 of permitted organic fertilizers applied annually. 30 Mg ha-1 of compost ploughed in before potato planting. Bio-pesticides(Bacillus thuringiensis) were used to control potato beetle. Biopesticides and hoeing/tillage used to control pests and weeds respectively
conventional agriculture
Mineral NPK fertilizers applied annually. Synthetic pesticides used to control pests and weeds. Crop residues ploughed in every second year
