Planting
With the Agriculture Skill learned a  Tilled Field can be built using the Till Field action. Having  Any Hoe equipped decreases both the Phlegm cost and the time it takes to build a Tilled Field.
To being Planting crops, you must first prepare your Tilled Field with  Humus. Select the Humus you wish to add and right-click it onto your Tilled Field. For a fresh Tilled Field this will require 5x Humus. After your first planting, the Upkeep can be reduced and subsequent planting will require less Humus. Once your Tilled Field is prepared, select the Seeds you wish to plant and right-click them onto the Tilled Field as well. Reducing a Tilled Field's Upkeep will also reduce the number of Seeds needed for Planting. Right-clicking on a Planted Field and selecting "Rip Up" allows you to remove the immature plants in case of accidentally Planting the wrong Seed. There is no penalty to Tilled Fields stats to do this, besides the loss of the Seeds. Once the desired Seeds have been Planted, you can Fertilize your Tilled Field to modify your crop's Influence, Upkeep, Speed, and Plenty. However, each  Fertilizer used reduces the effectiveness of next. Fertilizer can be added by selecting the desired Fertilizer and Right-clicking in on the Tilled Field.
Influence
A Tilled Field has four Influence bars - Red, Blue, Green, and Pink. Each crop has a bar which its crops Influence and two which it is in turn Influenced by. The Tier of crops which will grow are determined by the sum of the two bars it is Influenced by. When a Tilled Field is Harvested, with the Three-field System Skill learned, the bar which your crop Influences will increase by 5 times the Influence Percentage and the other three bars will be reduced by 5. The increase will be less if you have not yet learned Three-field System. Influence Percentage is affected by the Fertilizer used during Planting.

This table shows a way to get Tier 3 crops (Wanted Result) while getting particular Tier 2 products (2nd Rotation). In this case you want the second crop to actually use influence bar raised by first crop, in order to get higher tier results while raising influence for the final product. Items in brackets in 3rd column are possible 2nd tier products you may receive.
NOTE: In the above table Potato can be used instead of cabbage, and Tobacco can be used instead of cotton.
 Crop Table by Lusewing  Crop Table by Murphy Farming Purity
The Purity of crops Harvested from a Tilled Field is based on a combination of the Purity of the Tilled Field, the Purity of the Seeds used when Planting, and chance, which may increase or decrease the Purity of a Harvest by a few percent. Each time the Harvest is higher than the Tilled Field's Purity that Field's Purity will permanently increase by up to 1%.
Destroying a Tilled Field
A Tilled Field can't be  Destroyed by normal means, but requires the use of  Coarse Salt. To Destroy a Tilled Field select a Coarse Salt and right-click on the Tilled Field. You will need enough to first lower the Tilled Field's Purity to 0, after that, each subsequent Coarse Salt added will deal damage. Each Coarse Salt reduces the Purity by 5% or deals 20% of damage.
Upkeep
Upkeep affects the amount of resources needed to replant a Tilled Field - the lower its Upkeep the less Humus and Seeds will be used. Normally a Tilled Field's Upkeep has a lower Cap of 50%, however, once the Plantation Management skill has been learned, with Any Hoe equipped, you can right-click a Tilled Field and select "Tend" to permanently reduce it's Upkeep Cap. This reduction is based off the type of Hoe used. After each Planting your Tilled Field's Upkeep will drop 5%, additionally Upkeep can be further reduced by the Fertilizer used during Planting, down to it's Cap.
If a  Crow lands anywhere on your Tilled Field, it will increase that Field's Upkeep to 600%. Placing a Scarecrow nearby, will prevent this from happening.
Scarecrows
If a Crow lands anywhere on your Tilled Field, it will increase that Field's Upkeep to 600%. A Scarecrow, when placed nearby, will prevent Crows from landing on your Tilled Fields.
NOTE: The entire Tilled Field must be withing the radius of the Scarecrow's protection to prevent Crows from landing.
If a Crow does land in your Tilled Field the most effective recourse is to Destroy it with Coarse Salt if the Purity is low, or using 30x Humus and 1x  Potato Chunk or 1x  Wild Tuber to reset your Tilled Field to 100% Upkeep.
Speed
Speed reduces the time it takes for crops Planted in a Tilled Field to reach maturity. Speed is affected by the Fertilizer used during Planting. As Speed affects the time remaining not the total time, it is advised to use Speed Fertilizers early in Planting as they be progressively less effective the closer the crops are to Harvest.
The base growth time:
Plenty
Plenty increases the amount of crops you receive when Harvesting a Tilled Field. While Plenty is affected by the Fertilizer used during Planting, a bonus is also given at the time of Planting which is based on chance and your  Stocks & Cultivars. When your crops have matured, or reached the desired stage, right-click on your Tilled Field and select "Harvest". After a Tilled Field is Harvested, Influence, Speed, and Plenty are reset.
Harvesting
When crops are mature right-clicking on a Tilled Field will give you the ability to Harvest crops. Using the Salem Store bought  Reaping Scythe will dramatically increase the speed which you harvest mature crops from a Tilled Field.
Fertilizer
Once a Tilled Field has been prepared with Humus and Planted with seeds, you can add Fertilizer to your Tilled Field to modify your crop's Influence, Upkeep, Speed, and Plenty. However, each Fertilizer used reduces the less effectiveness of next. Fertilizer can be added by selecting the desired Fertilizer and Right-clicking in on the Tilled Field.
NOTE Values for Influence are factored with the bonus from having learned Three-field System.
