Title

Nutrient saturation of crop monocultures and agroforestry indicated by nutrient response efficiency

Other claims from this paper (10)

Intervention effect Crop yield, plant-available nutrients and NRE were comparable between alley-cropping agroforestry and cropland monocultures.
Observation Trees in agroforestry had high nutrient response efficiency.
Association Trees in agroforestry contributed to nutrient retention of the agroforestry system as a whole.

Harold V. Eck; Ronald G. Davis Agronomy Journal 1971. doi:10.2134/agronj1971.00021962006300060034x

Other claims from this paper (11)

Intervention effect Deep plowing tended to decrease root yield of sugarbeets.
Intervention effect Deep plowing tended to decrease root yield of soybeans.
Intervention effect Deep plowing had little effect on root yield of cabbage.
Association Root yields of plants decreased with depth on soil rototilled to 20 cm or moldboard plowed to 90 cm.
Intervention effect Application of 22,400 kg/ha of Na2CO3 at the 90 cm plow depth made roots of plants tend to be evenly distributed throughout the 90 cm profile.
Intervention effect Profile modification enhanced root activity of plants, as measured by top-root ratios.
Method / resource Top-root ratios are better indicators of root activity than top or root yields alone.
Observation Sr 85 uptake showed that roots in the 70 to 90 cm zone were as active as roots in the 0 to 20 cm zone.
Intervention effect Na2CO3 tended to increase root weights in its zone of application.
Intervention effect Na2CO3 reduced radiostrontium uptake by about eightfold compared with similarly placed radiostrontium without Na2CO3.
Association Na2CO3 indicates a decrease in root activity.
