Other claims from this paper (12)

Association February soil nitrate did not predict nitrogen available in early vegetation.
Association Early spring soil nitrate had very low correlation with sugar yield.
Association April/May nitrate in the upper soil layer correlated highly significantly with sugar yield.
Association Maximum sugar yield occurred with 220 kg N/ha April/May soil nitrate.
Observation Sugar yield had a wide nitrogen optimum range.
Intervention effect Nitrogen deviations below 50 kg N/ha from optimum did not significantly change sugar yield.
Association More late-available deep nitrogen decreased sugar content.
Association More late-available deep nitrogen increased sodium.
Mechanism Early nitrogen application may leach under heavy rain and harm juice purity and sugar content.
Recommendation Apply nitrogen one or two weeks after seeding for maximum sugar yield.
Recommendation Local experience may suffice to set nitrogen fertilizer because of the wide optimum.
Recommendation In special cases measure April soil nitrate and supplement fertilizer to 220 kg N/ha.
