In these videos, two farmers in the Willamette Valley, Peter Kenagy and Ron Pearmine, talk about the history of their farms, the bond they have with the land, and why conserving and enhancing wildlife habitat on their farms is so important to them.

Historical liming document with useful information pertaining to the effects of low soil pH on the macro and micro nutrient content in peas, carrots, onions, cauliflower, and celery, and may be useful in diagnosing soil and plant problems based on plant tissue analysis.

Clubroot is becoming an increasing problem on Willamette Valley vegetable farms. Most cultivated brassica crops (broccoli, cauliflower, cabbage, etc.) are highly susceptible to the disease, which is caused by the soilborne fungus Plasmodiophora brassicae. In severe cases it can cause significant crop losses, and heavily infested fields may be taken out of production. Once a field is infected, eliminating the pathogen is difficult if not impossible because its thick walled resting spores have been shown to remain viable in soil for up to 18 years. As a result, once pathogen populations have developed to economically damaging levels, the goal of the farmer is to manage rather than eradicate the disease. One effective control strategy is to raise the soil pH to ≥7.2 through liming.

This article looks at nitrogen utilization by snap beans grown in the Willamette Valley of Oregon and provides information necessary to make N fertilizer timing and rate decisions to maximize N uptake while minimizing environmental losses.
