Good Crops You Don’t Eat + Passive Irrigation Systems
Audio Brief
Show transcript
This episode covers strategies for market gardeners to diversify income using non food crops and solve common agricultural challenges.
There are three key takeaways. First expanding into non food crops like gourds and luffas creates high margin opportunities. Second gravity fed irrigation systems require specific elevation calculations to function properly. Third managing alkaline soil for acid loving plants is often best handled through raised beds rather than native soil alteration.
Focusing on the cucurbit family allows farmers to maximize land use and profit margins without significantly changing their growing practices. Crops such as decorative gourds broomcorn and luffas sell at a high premium for fall markets or holiday gift baskets. Some options like pumpkins even serve dual purposes by providing edible squash blossoms early in the season and the main fruit for decoration later.
For farms with limited water pressure or off grid setups passive irrigation offers a highly effective and scalable solution. Setting up a gravity fed system requires precise math to ensure drip lines function correctly. Growers can calculate a gain of zero point four three three PSI for every single foot of tank elevation allowing them to design custom watering systems anywhere on the property.
Growing acid loving plants like blueberries in naturally alkaline environments presents a persistent challenge for many farmers. While organic amendments like sulfur and sphagnum peat moss can slowly lower soil pH over time they require constant monitoring and professional agronomist guidance. Instead of fighting the native soil chemistry growers can achieve immediate success by utilizing raised beds filled with specialized pre mixed acidic compost.
Implementing these diversification strategies and practical farm solutions will help growers maximize their land use and profitability.
Episode Overview
- This episode of "Growers Daily" focuses on non-food crops that market gardeners and farmers can grow to diversify their offerings and income streams.
- The host, Farmer Jesse, explores the cucurbit family, highlighting crops like decorative gourds, luffas, and pumpkins, which offer both edible and non-edible parts and products.
- The discussion covers practical aspects of growing these crops, including their space, fertility, and maintenance requirements, and how to effectively market them.
- Additionally, the episode addresses listener questions on passive irrigation systems and lowering soil pH organically for blueberries, providing actionable advice for growers facing these challenges.
- This content is valuable for farmers looking to maximize their land use, expand their product lines with high-margin items, and solve common agricultural problems using practical, scalable methods.
Key Concepts
- Diversification through Non-Food Crops: Growing non-food crops like gourds, luffas, and broomcorn can significantly diversify a farm's income. These items often sell at a higher premium than traditional vegetables, especially when marketed correctly, such as for fall decorations or in gift baskets.
- The Utility of the Cucurbit Family: The cucurbit family offers a wide range of products beyond food. For example, gourds can be used for birdhouses, ladles, and musical instruments, while luffas provide excellent natural sponges. Some crops, like pumpkins, even offer dual purposes—jack-o'-lanterns for decoration and squash blossoms for eating.
- Passive Irrigation Systems: Setting up a gravity-fed passive irrigation system is a viable option for farms with limited water pressure. By elevating a water tank, growers can generate enough PSI (pounds per square inch) to run drip lines, calculating about 0.433 PSI for every foot of elevation.
- Managing Soil pH for Acid-Loving Plants: Growing acid-loving plants like blueberries in naturally alkaline soil can be challenging. While organic options like sulfur and sphagnum peat moss exist, they require careful application based on soil tests. For raised beds, using specialized, pre-mixed acidic soil or compost can be a more manageable solution.
Quotes
- At 2:46 - "let's start with discussing that whole cucurbit family in this first segment because it is maybe the biggest in terms of like producing crops that are not necessarily food" - This highlights the significant potential of the cucurbit family for diversifying farm products beyond traditional food items.
- At 8:58 - "you gain like .433 PSI for every foot of height for the top of the water" - This explains the fundamental calculation needed to design an effective gravity-fed irrigation system, a crucial skill for off-grid or low-pressure farming.
- At 10:48 - "both of those things can help to lower the pH organically just with things like sulfur, make sure you are adding it at the recommendations of an agronomist" - This emphasizes the importance of professional guidance when attempting to alter soil chemistry organically, ensuring safe and effective results.
Takeaways
- Explore growing non-food crops like decorative gourds or luffas to create high-margin products for fall markets or holiday gift baskets.
- When setting up a gravity-fed irrigation system, calculate the required height for your water tank based on the PSI needs of your specific drip lines (using the 0.433 PSI per foot rule).
- If struggling with alkaline soil, consider growing acid-loving plants like blueberries in raised beds with custom-mixed acidic soil or compost, rather than trying to alter the native soil's pH.
