Advancements in the area of agriculture has started to depend on technology sources for better yield and technology advancements have in the areas of irrigation, and drainage. even the packing, processing, and marketing of agricultural products are also the activities which are influenced by science. global positioning satellite (gps) technology has vastly innovated agriculture. how does gps technology contribute to farming by making planting, fertilization, and crop harvesting easier? a) it tells the farmer when rain is coming. b) it cost too much, so it makes crops more expensive. c) gps makes the farmer lazy because he doesn't have to work as hard. d) gps technology has led development of robotic tractors for planting, fertilization, and crop harvesting.

Answer is D. GPS technology has led development of robotic tractors for planting, fertilization, and crop harvesting.

Before advancement of the technology it was difficult for farmers to carry out farm planning, field mapping, soil sampling, tractor guidance, crop scouting, and yield mapping. But with the development of Global Positioning System (GPS), farmers can take informed decision about application of pesticides, herbicides, and fertilizers, and better control to disperse these chemicals. Farmers can use data in reducing expense, better harvesting technique and a higher yield, and creating a more environmentally friendly farm.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
