 | Using Sea Lettuce as a soil amendment in Potato Production; and reduced fertility trial
Research performed on the farm of Jeff and Jason Smallman in O'Leary explored the use of sea letuce as a soil amendment in potato production. Research was performed with the assistance of Agriculture and Agri-Food Canada Science and Technology Branch, under the management of Roger Henry.
Research was also performed on reduced synthetic fertilizer usage to see how the potato crop would perform. |

| Nutrient Management Planning and Liquid Manure Injection - Silage Corn On-farm Trials
Liquid Manure Injection involves injecting liquid hog or dairy manure directly into the soil with a standard liquid manure tanker equipped with a full tillage manure injector. This practice has potential to increase crop yields, reduce input costs and benefit the environment. |

| Nutrient Management Planning - On-farm Potato Grain Hay Trials
A Nutrient Management Plan (NMP) is a document that describes the production practices that a farm manager currently uses and/or will implement to sustain livestock and/or crop production in a manner that is both environmentally and economically sound. |

| Nitrogen Management for Corn: General Fertilizer Recommendations
Sound nitrogen management for corn makes good
economic sense. Optimal nitrogen fertilization is
essential for achieving a successful, high yielding corn
crop. Inadequate nitrogen inputs result in loss of silage
or grain yield. Excessive nitrogen inputs reduce profitability
and can delay maturity for grain corn. Applying
the optimal fertilizer nitrogen rate achieves good crop
yield and results in maximum economic return. |

| Nitrogen Management for Corn: Pre-Sidedress Soil Nitrate Test (PSNT)
The Pre-sidedress Soil Nitrate Test (PSNT) can be
used to improve fertilizer nitrogen recommendations
for silage or grain corn production. The factsheet
Nitrogen Management for Corn: General Fertilizer
Recommendations can be used to estimate the corn
fertilizer nitrogen requirement using average values for
manure, crop and soil nitrogen credits. However, the
actual nitrogen benefits from these sources can vary
from field-to-field and year-to-year. The PSNT uses a
soil sample taken when the corn is at the six-leaf stage
(about 8 to 10" high) to decide how much sidedress
nitrogen fertilizer to apply on an individual field. This
factsheet outlines preliminary recommendations for
fertilizer nitrogen management for corn based on the
PSNT. |
