Weeds steal the nutrients from the soil that the crops need. Some weeds grow so thick that they choke out the crop. If the weeds get tall enough, they will shade out the crops so that they can not get the sunlight they need.

∙ 9y agoAir space, heat, light, moisture, nutrients, and space are what weeds compete for. They generally do quite well in doing so since they can colonize degraded or disturbed sites which are too high or low in moisture- and nutrient-retention for edibles and ornamentals to thrive.

∙ 8y agoQuick intake of moisture and nutrients, rapid expansion into horizontal and vertical spaces, and tolerance of low living standards are ways whereby weeds compete with crops for resources. Weeds manage to flourish in high- and low-moisture and nutrient situations on disturbed soils. They spread in more than one way -- by rhizomes, roots, seeds, and stolons -- so that they assert first claims to sub-surface and surface moisture and nutrients.

How do weeds compete for resources?
How do weeds compete for resources?if weeds steal resources from a farmer's crop, do they steal ?the roots of weeds absorb nutrients from the soil,meaning fewer nutrients are available to the crop plants.the roots of weeds absorb water from the soil, so less is available to the crop plants.the leaves of weeds absorb carbon dioxide from the air,so less is available to the crop plants.the leaves of tall weeds can also absorb light before it reaches the crop.
Why do crops not grow well in a field if there are a lot of weeds?
Because the weeds are using up many of the resources such as water and plant nutrients intended for the crop.
What are the effect of weed on crop and animals?
because plants need light and space to be able to grow if there are weeds there then there is no space and they steal all the light, they can effectively choke a plant to death i they are so riddled with weeds. Weeds compete with other plants for nutrients from the soil. Weeds in a maize crop would take nutrients the maize needs.
What harm can weeds do to crop if they grow together?
Weeds reduce farm and forest productivity, theyinvade crops, smother pastures and in some cases can harm livestock. They aggressively compete for water, nutrients and sunlight, resulting in reduced crop yield and poor crop quality.Dec 18, 2014
How do weeds cause damage to the crop plants. Mention any two ways?
By stealing 1) water and 2) plant nutrients away from the crop.

What are the effects of weeds in the growth of the plant?
weeds use up the nutrients from the land and as a result food crops do not get enough nutrition ultimately it hinders the growth of the food crop
What are the benefits of using herbicides?
weeds compete with the crop for water, nutrients, sunlight and space. using herbecides gives your crops a better chance for survval
Is the yield of beetroots affected by weeds?
The yield of ANY crop is affected by weeds. While you can't always see the effects, the weeds are stealing crop nutrients and water from the crop.
What types of weeds affect wheat crop?
the weeds could eat you up!
What does roundup ready mean in plant science?
Roundup is the name of a herbicide used by farmers to kill weeds. A plant is said to be roundup ready if it is resistant to roundup, so that you can spray a field with roundup and it will kill the weeds but won't kill the roundup ready crop.
Why weeds are a problem to crop growers?
Weeds are a problem to crop growers because they compete with the plants for air, water, and nutrients, and they usually win. They choke the plants, and their hedge like features don't allow the plants to get any sunlight. They harbour pests and diseases within them. And, of course, they look bad, and make the entire garden or flower bed look bad too.
