The aim is to assess how fodder crop rotations affect soil fertility and crop productivity in northern climates.
Comprehensive soil assessment conducted in soddy-podzolic soils.
Evaluation of green mass of annual and perennial plants.
Long-term field experiment initiated in 1978 by the Institute of Agrobiotechnologies.
Use of organic and mineral fertilisers increased potato yield to 3.3–5.5 t dry weight/ha.
Green mass of perennial grasses yielded 9.2–12.0 t dry weight/ha, improving feed quality.
Annual grasses produced 2.9–3.4 t dry weight/ha, with corresponding feed unit increases.

Brovarova et al. (2026) studied this question.
