- When Chris mows the grass, she faces a choice between discarding the clippings and leaving them on the lawn. How would each choice influence the nutrient content of the soil? Explain your answerWhich three soil colours would suggest the following conditions in the soil 1. Poor drainage 2. Reduced compounds of manganese 3. Well drained and aeration soilIf a soil when sampled from the field weighed 30g(fresh weight) and after oven drying at 105°C overnight it weighed 25g( oven dry weight), what would be the moisture percentage?

True or FalseHow to develop teaching and learning material to teach the concept nature of soil and how to use the teaching and learning material at the classroom. And reason for choosing that teaching and learning materialThe high acidity of the soil means less capacity to bind positively charged ions. True or False?

Writing Prompt / Indicación de Escritura: A group of students wanted to test how the amount of water a plant receives affects its growth. To test this, students placed three identical plants in identical pots using the same soil. Each plant received a different amount of water each day, and plant growth was measured at the end of each week. Write a PROCEDURE the students can follow to conduct this experiment. * Your answer Submit Never submit passwords through Google Forms.
- Name two soil properties that can affect infiltration rates. How does application rate affect infiltration? Why are infiltration rates typically higher in a sandy than in a clay soil?When the soil is acidic, plants cannot grow on it. True or FalseMalathion is an organophosphate pesticide that is used often in residential and commercial landscaping. A landscaping company came and applied the pesticide to a lawn and after a couple of days. An environmental science student sampled the soil and analyzed the pesticide content. The student found the soil concentration of malathion to be 6.26 ppm. Assume a soil organic content of 1.5%, a soil particle density of 2.0 mg/L, and a soil porosity of 45%. If it rains the next day and water mixes well with the soil, estimate the concentration of malathion in the soil water.
