Working the land(Periods 1 Warming up and Reading)

tomatoes are warm season plants requiring at least six hours per day.temperatures are very important.most varieties of tomatoes will not set fruit unless the average nighttime temperature stays above 55 degrees.if nighttime temperatures are expected to drop below 55 degrees,protect the plants using a polyethylene film.one of the most common problems with tomatoes is called blossom end rot which appears as a gray or dark leathery scar or rot on the blossom end of the fruit.it is usually caused by sudden or inconsistent moisture levels in the soil.it can also be caused by a lack of calcium in the soil.another common problem of tomatoes is blossom drop.this can occur if nighttime temperatures drop below 55 degrees and plants are not protected.germination and tube growth are so slow that the blossoms drop off before they can be fertilized.3)peaspeas are a frost-hardy,cool-season vegetable that can be grown throughout most of the united states,wherever a cool season of sufficient duration exists.for gardening purposes,peas may be classified as garden peas (english peas),snap peas and snow peas (sugar peas).garden pea varieties have smooth or wrinkled seeds.the smooth-seeded varieties tend to have more starch than the wrinkled-seeded varieties.the wrinkled-seeded varieties are generally sweeter and usually preferred for home use.the smooth-seeded types are used more often to produce ripe seeds that are used like dry beans and to make split-pea soup.snap peas have been developed from garden peas to have low-fiber pods that can be snapped and eaten along with the immature peas inside.snow peas are meant to be harvested as flat,tender pods before the peas inside develop at all.the southern pea (cowpea) is an entirely different warm-season vegetable that is planted and grown in the same manner as beans.

2.is organic food safe?yes.organic food is as safe to consume as any other kind of food.just as with any kind of produce,consumers should wash before consuming to ensure maximum cleanliness.as cited above,organic produce contains significantly lower levels of pesticide residues than conventional produce.it is a common misconception that organic food could be at greater risk of e.coli contamination because of raw manure application although conventional farmers commonly apply tons of raw manure as well with no regulation whatsoever.organic standards set strict guidelines on manure use in organic farming:either it must be first composted,or it must be applied at least 90 days before harvest,which allows ample time for microbial breakdown of any pathogens.
