3. Proper soil composition is important for plants. Some elements, like nitrogen, are known to increase plant growth. A researcher wants to develop a soil with added minerals and nutrients to determine the best composition to promote healthy plant growth. What are good positive and negative controls?

15. What process is responsible for the increase in the total negative charge as soil pH increases? A. Dehydration reaction B. Deprotonation C. Protonation D. H+ bond formation
Select all that are true regarding soil a. the most abundant element of soil is inorganic mater b. plants passively acquire cations by using ATP to pump H+ into the soil c. soil plays key roles in water regulation and buffering of pollutants d. soil is an essential source of carbon for plants e. plants use H+ from photosynthesis to acquire cations f. anions are unbound in the soil and freely travel into plant roots with water g. cation exchange is required because cations are bound to negatively charged soil particles h. H+ works well for the cation exchange because it is a small molecule with a strong charge 2.

Observation: I want to know what effect salt has on the growth of grass. So I measure out 3 equal-sized squares of grass out the back of the Green Building. The first square of lawn I water with 5 liters of pure water from a watering can every day. The second square of lawn I water with 5 liters of pure water with 2 grams of salt mixed in, every day. The third square of lawn I water with 5 liters of pure water with 4 grams of salt mixed in, every day. I measure the height of the grass after 14 days and note the following observations. The first square is green and 15 cm high. The second square is greeny-yellow and 6 cm high. The third square is yellowy-brown and looks dead and is only 2cm high. What could we infer about the effect salt has on the growth of grass?
