Answer rating: 100% (QA)
To determine the amount of oat straw required per kilogram of potato tops waste we need to consider the CN ratio and moisture content of both materials Lets calculate the values step by step 1 Calculate the CN ratio of potato tops waste The CN ratio of potato tops waste is not provided However based on general estimates the CN ratio of potato tops waste ranges from 201 to 301 Lets assume it to be 251 2 Calculate the CN ratio of oat straw The CN ratio of oat straw is not provided either However the CN ratio of straw typically falls within the range of 501 to 1001 Lets assume it to be 751 3 Calculate the initial CN ratio of the compost mix Since we want an initial CN ratio of 30 we need to find the right combination of potato tops waste and oat straw that will achieve this ratio Lets assume x represents the amount of oat straw in kilograms required per kilogram of potato tops waste The equation to calculate the CN ratio is CN ratio of potato tops waste weight of potato tops waste CN ratio of oat straw weight of oat straw CN ratio of compost mix total weight of the mix 25 1 75 x 30 1 x 25 75x 30 30x 45x 5 x 545 x 01111 Therefore approximately 01111 kilograms of oat straw is required per kilogram of potato tops waste to achieve an initial CN ratio of 30 4 Calculate the moisture content of the compost mix To determine the moisture content of the compost mix we need to consider the moisture content of both materials Since moisture is typically expressed as a percentage we need to find the weighted average based on the weights of each material ...
