Weeds can play a valuable role in the farm ecosystem. The better you know their characteristics, the better they can contribute positively to successful farming without becoming harmful.
All plants that compete with our crops for nutrients, water and light, and reduce their harvest and quality are considered weeds. Some plants may also poison domesticated animals when growing on pasture land.
It is important to know which pathogens create damage in the fields. Proper determination of the pathogen is the first step to effective pest and disease management.
it is the grower’s task to make sure that the weeds present do not exceed damaging thresholds that limit crop yields. In this chapter, we will address practical weed management techniques for the organic producer.

The biggest challenge that organic producers face today is weed management. This chapter is devoted to weed biology, which is an aspect of weeds necessary in understanding how to manage them.
Weeds become a farming risk when they reduce crop yields or lower crop quality. Risks due to weeds include:
Organic farmers have different approaches to supplying crop needs compared to conventional farmers who provide fertility by numerous synthetic fertilizers. See the table below for differences between organic and conventional fertilizers.
