How to Start a Successful and Profitable Cashew Nut Farming Business in Kenya: From Planting to Harvest

Cashew nut is made up of a fruit in which the kernel is embedded. The real fruit of the cashew is commonly a nut. It is a kidney- or heart-shaped achene, in any normal variety. Its color varies from bottle green to grayish brown (dried fruit). It is attached to the end of a fleshy footstalk or peduncle, which is in fact the receptacle of the flower that is broadened and swollen and forms the false fruit.

Cashew Nuts

The nut is composed of kernel and pericarp or shell. The kernel is slightly curved back on itself and forms two cotyledons, representing about 20–25% of the nuts weight. It is wrapped in a thin, difficult to remove peel (testa), reddish-brown membrane, which in turn approximates to 5% of the whole nut.

But how do you go from planting a few seeds to running a successful cashew nut business? I’m going to take you through everything you need to know to get your profitable cashew nut farming business up and running—from planting to harvest!

The Fruits That Don't Mind Acidic Soils: A Special Focus on Blueberries

Acidic soils are generally thought to be BAD for farming. What if I told you that there is a very expensive fruit that loves growing in acidic soils? Well, don't be surprised because that is true and the fruit is none other than blueberries. If you've done a little research on blueberry farming, you have probably heard that the soil pH matters a lot, but what does that really mean? And also why is it so important for fruit farming?

A Blueberry Bush

What is Soil pH and Why Does It Matter?

First things first, let us talk about what pH is. Soil pH refers to the level of acidity or alkalinity in the soil. It’s measured on a scale from 0 to 14 with 7 being neutral, and anything lower than 7 is acidic, and anything higher than 7 is alkaline  or basic. For most crops pH is a key factor in how well they grow because it affects nutrient availability, soil health and even the microbes that live in the soil.

In the case of blueberries, pH is even more critical as these little berries prefer a soil pH that’s on the acidic side, typically between 4.5 and 5.5. If the soil becomes too alkaline blueberries won’t be able to absorb the nutrients they need to thrive. This can then lead to poor growth, weak plants and resulting to lower yields.

Read more on  How To Start Commercial Blueberry Farming in Kenya

Best pH Range for Blueberries

Blueberries are very picky about their soil and they have a sweet spot when it comes to pH. They like it on the acidic side. And for the best results blueberry plants thrive when the soil pH is between 4.5 and 5.5. At this level, they can absorb nutrients like nitrogen, phosphorus, and potassium which are the three essential elements for strong growth and fruit production.

But why is that? Well, when the soil is too acidic, that is below pH 4.5, or too alkaline, that is above pH 5.5, the blueberries have a harder time getting the nutrients they need. This can then lead to poor development, unhealthy plants, and ultimately a disappointing harvest.

How pH Affects Nutrient Availability

What then happens to the nutrients in the soil when the pH is off? The key here is that different nutrients become available at different pH levels. Some nutrients are easier for plants to take up in acidic soils, while others are more available in the more alkaline conditions.

For blueberries nutrients like iron, manganese and zinc are more readily available when the soil is acidic. These nutrients are vital or very important for blueberry health and growth. If the soil pH isn’t right your plants may show signs of nutrient deficiencies, for example, blueberries with an iron deficiency can develop yellow leaves with green veins, a condition called chlorosis. This is often a sign that the soil pH is too high, that is alkaline, making iron hard for the plants to absorb.

In contrast, when the pH is too low, highly acidic, blueberries may have a struggle to take up calcium and magnesium. This can then lead to stunted growth and poor fruit develop, therefore getting the pH right is a delicate balance.

Blueberry Farming

Soil Microbes and pH: The Hidden Helpers

Soil microbes are tiny organisms that play quite a huge role in maintaining soil health. They help break down organic matter making nutrients available for plants. They also help with soil structure which promotes good root growth.

The pH of your soil has a direct impact on which microbes are present in the soil. In acidic soils like the ones blueberries prefer, beneficial fungi like mycorrhizal fungi thrive. These fungi have a symbiotic relationship with blueberry roots helping them absorb more nutrients, especially phosphorus. Without these fungi blueberries would have a much harder time getting the much needed nutrition they need to grow.

When the soil pH is out of whack it can affect these microbes hence reducing their effectiveness, this in turn can hurt the health of your blueberry plants.

Soil pH and Blueberry Yield: The Bottom Line

The relationship between pH and blueberry yield is pretty straightforward; if the pH is off your berries won’t be as big, sweet or even plentiful. Blueberries need just the right balance of acidity to ensure that they can access all the nutrients they need for strong growth and high fruit production.

When the soil is within the ideal pH range the blueberries tend to have better fruit quality meaning the berries will be larger, more flavorful and more uniform. If the pH is too high or too low the fruit may be smaller, less flavorful or even fail to develop altogether. And let’s face it, nobody wants a crop of sad, tiny blueberries that don’t taste great.

How pH Affects Productivity and How to Adjust it for Blueberries

If the soil pH is too high for blueberries don’t worry as you can fix it. Here are a few common ways that farmers use to adjust soil pH to make it more acidic;

1. Elemental Sulfur: This is one of the most common methods for lowering soil pH. When sulfur is added to the soil it then reacts with water and oxygen to form sulfuric acid which then does lowers the pH. Just keep in mind that it can take several months for sulfur to have a noticeable effect so patience is key.

2. Organic Matter: Addition of organic materials like pine bark, pine needles or peat moss can help lower the pH naturally. These materials are acidic and can help create just the perfect environment for your blueberries to thrive.

3. Aluminum Sulfate: If you do need a quicker fix aluminum sulfate is another good of the options. It works faster than elemental sulfur but should be used carefully as its overuse can lead to aluminum toxicity which can then damage the plants.

It is very important to note that adjusting pH is an ongoing process. The soil pH can shift over time due to factors like rainfall, fertilization and irrigation and that’s why regular soil testing is key to making sure you are keeping things in check.

Factors That Affect Soil pH in Blueberry Farming

The soil pH doesn’t stay the same forever. There are several factors that can influence it throughout the years including;

1.  Climate: The areas with more rainfall tend to have more acidic soils. Rainwater itself is slightly acidic which can then naturally lower pH over time. On the other hand, the areas with dry climates might have more alkaline soils.

2. Irrigation Practices: The type of water you use can affect the soil pH. If you are using well water or water that is high in minerals, it could easily raise the pH. Similarly, frequent irrigation in regions with alkaline water can also cause the soil to become more alkaline.

3.  Fertilization: The type of fertilizer you use can also have an impact on soil pH. Some fertilizers like ammonium sulfate can lower pH while others like calcium nitrate can raise it. You are advised to always choose a fertilizer that matches your soil’s needs.

4. Soil Amendments: Adding materials like compost, lime or even manure can also affect pH. Lime, for example, is used to raise pH in soils that are too acidic. This is important to keep in mind if you are rotating crops or adding organic matter to the soil.

Long-Term Effects of pH Management

Managing soil pH isn’t a one-time task; it is something you will need to keep an eye on throughout the life of your blueberry plants. Over time, the pH may fluctuate, especially if you’re in an area with a lot of rainfall or even irrigation.

It is also very important to remember that soil pH management has environmental impacts. Over acidifying your soil with excess sulfur or other acidifying agents can indeed harm the surrounding ecosystem and that is why it is very crucial to test your soil regularly and make small adjustments instead of big, drastic changes.

To conclude, we do see that the soil pH does plays a huge role in blueberry farming and getting it right can make all the difference in your yield and fruit quality. Blueberries do prefer acidic soils. When the pH is in the sweet spot of between 4.5 and 5.5 they can access the nutrients they need to thrive. What is the result? You get bigger, sweeter berries, healthier plants and even higher yields.
