ite expectancy access to irrigation H.O cts 2. Irrigation is commonly needed with shallow rooted crops because...(circle best answer) iteracy individual land ownership a. their crop H20 use is much larger than deep rooted crops b. their transpiration rate is much higher than in deep rooted plants c. they are commonly grown on clay soils that make it difficult for roots to grow deeper in the soil d, their roots explore less soil volume compared to deep rooted crops e. their roots store HiO used later during the growth cycle Define plant available Ho. 3. soil compaction imits plant growth because of a. increased pore space and water infiltration 4. (cicle best answer) increased clay content and organic matter c. reduced volume of soil pore space which decreases air flow and HO availability d. reduced plant available HO and increased soil clay content+ e. decreased plant available H2O and clay content ovalable HO and clay content 5. Certain soil properties s or processes are strongly influenced by soil texture. Which of the following is correct for a clay soil compared to a sand (circle best answer. .. 9. lower infiltration, lower percolation, more plant available water 10.lower infiltration, lower percolation. less plant available water, higher compaction, lower runoff 11. lower infitration, greater percolation, less plant available water. lower compaction. greater runoff 12. lower infitration. greater percolation, less plant available water, lower compaction, lower runoff soil texture influences the quantity of plant available H2O by a. less pore space and particle surface area reduces plant available H:0 in sit compared to sand b. more pore space and particle surface area reduces plant available HO in sit compared to clay compaction. greater runoffe 6. (circle best answer). · greater infiltration d. greaterrunoff in a clay reduces plant available HO compared to a ion in a sand increases plant available H:O com to a clay cle surface areo ces plant available HO in sond compared to sit 7 Circle best answer. soil texture represents the % by weight of sand clay, and silt Most fresh H:0 on the planet is groundwater..... DES represents the Daily Evaporation from Soil Chronic m Soil structure cannot influence how water moves through soil nded in regions with a high HO tableExplanation / Answer
2. Answer :d. Explanation : shallow roots cover few area. So irrigation is necessary. 3 . Plant available water is defined as the water content between soil capacity and permanent wilting point. 4. Answer :C. Explanation :compaction is the removal of soil voids and this leads to blocking of nitrogen transfer which makes soil unsuitable.
