The third reason is that the lentils in the cycle are low in nitrogen.

In the years to come, the situation will remain the same: drought and heat waves will continue to rise and fill phases. In France, “we expect yields to decline in the southwest and stagnation in the northeast.” Globally, if you believe the map he shares, the upward trend in yields would be concentrated in Russia and parts of the United States:
